Good luck everyone! I'm presuming that, despite shock all round, this is good news for the business, customers, and importantly, employees. And please don't forget the volunteers, like many of the people on this forum. Personally, I've created over 900 videos on YouTube in my InAffinity channel and learned a huge amount about photo editing in the process. Affinity Photo (and I presume the other apps) is a brilliant product and I am in awe of how you have created this.
Well done also on the four commitments. Wisely thought out and should help calm nerves all round.
I can empathise significantly. I was a sofware engineer in small and large companies, UK and global. I moved to marketing and general business and eventually managing mergers and acquisitions in Agilent Technologies (the $10B spin-off from HP of its original businesses), where I was the Workplace Services (facilities, security, H&S, etc) global M&A manager. The most critical element of this, amidst all the IT, HR, Finance, WPS, etc, was cultural integration. One thing we found was that when acquired, people in a company will go along with many changes for the first 100 day, but will want to settle down soon after that.
Canva sounds like a good fit with Serif but there will be differences and how these are handled is so important. Australian and UK cultures have a lot of overlap, but they are not the same. Key will be leadership, which is often misunderstood. The first layer of understanding for this is followership. Without followers, you may be a manager but you are not a leader. Leaders also need to understand psychology, a subject I studied while writing the many pages on the changingminds.org website.
I could ramble further, but you've probably had enough by now and I have a photo competition to judge and potatoes to plant.
Best wishes to all the wonderful Serif, Affinity and Canva people

Understandable. Which is why the words have to be followed up with aligned actions. And the actions communicated. Trust is in a delicate place now and needs lots of TLC.

Has been discussed several times in the past if it is possible to install Affinity apps on different drives and that personalbackupstore may burst your c-drive.
you can use junctions as described below.
 

Attached is my complete set of notes about blend modes, now spread across 52 pages of A4.
These are significantly updated from the previous revision, with lots more 'recipes' and organisation of these under main topics, hopefully to make them more usable.
Enjoy.
Blend modes notes V5.pdf

Hi All,
We have just made 2.2 live across all App Stores and our website. As always, the feedback we have received from you all during this beta has been an incredible help in both shaping the new features as well as squashing many bugs!
The build we have released is the same as RC3 (build 2005), meaning for the time being whether you use the latest beta version or switch to using the release version they are the same. If you anticipate taking part in the next beta you may wish to keep your current beta version installed, as this will be updated on auto update when a new beta is available. This will either be a 2.2 patch if we feel one is needed, or moving straight onto a 2.3 beta.
It would be impossible for us to do what we do without your support, and I just wanted to say a huge thanks for everything you have contributed to this release.
All the best,
Ash

For the failure you experienced, I agree.
There are other failures where that is not possible, e.g. where the complete file has not been read into memory, yet, and needs to be fully read before the app would be able to Save anyplace else. And I can conceive of scenarios where that might apply even for the message you got.
Cloud services can operate in many ways, and there are things they can do that will cause problems. Some examples:
Some services may rename the local files during their processing, which will cause a problem if an application like one of the Affinity apps creates the file initially, then Opens it, then writes into it. The cloud client may perform the rename after file creation, but before the Open, causing the Open to fail. Or, similarly, the cloud client may lock the local file during their processing, and then the Affinity app may experience a failure trying to Open, or trying to write.

I've just lost hours of critical work after "Save failed because ownership of the file could not be verified. The document must now be closed."
I re-edited the image. An early save worked. A later save didn't.
To say I'm unhappy would be an understatement.
Version 2.2.1 Affinity Photo
Edit: I tried resaving the original image (a jpg) with different algorithm (Lanczos) and restarted edit. I saved at regular points along the way. Eventually I hit the same barrier. I exported the original jpg as tiff and restarted, with the same effect. I also hit the same problem with a separate image which was a RAW .NEF file.

It's a new one on me and I'm still puzzled as to what exactly might be going on. I've not heard of this happening with other applications. It would be enormously helpful if AP is unable to save remotely that it gave you an option to save locally rather than crashing out.
Nevertheless I'm grateful for the knowledge and will follow your advice, Walt. Thanks!

YouTuber InAffinity has some great tutorials explaining all the basics, especially the older ones.
 

I have the same issue. See three examples with luminosity range mask in preview mode.
Mask in the first picture is ok, but as soon as the curve touches the uppest x-axis (second picture) pure white becomes suddenly black .
I'm able to partialy workaround it moving the most right node to the left. The curve in the third picture is very close to the second one, but pure white remains as is.
