Look in Pages studio Colour section.🙂

Yes, you need to se the Table panel. Tap Vertical Position.

@CleverFox2 -- I noted the same thing moments after posting.  So I reposted it (same problem, perhaps with forum?)  I sent a copy to SMASH.

Same issue on Smash... The forum only seems to like .mp4 files so I've converted it for you... hopefully others can view it?

That is correct upon opening the app for the first time.

We have not decided on the minimum spec yet but Affinity Publisher does not need Stage Manager to run on an iPad.

The reason it was removed was because it simply was not even close to being ready. When I was testing the feature at the time there were multiple issues with it that could not just be solved with a flick of the switch.
- The export settings were broken with tons of encoding artefacts across all settings. It just did not look good.
- On Windows you couldn't even export with specific settings because it required an encoding library that is not even native on many Windows versions.
- The camera options were limited and did not work work well with Artboards and large canvases. If you wanted the video to follow your brush strokes the camera would sporadically jump all over the place and you could just not keep track of what was going on. The camera would zoom in super far if you did small brush strokes, so you couldn't see the rest of the painting. If you were painting across several Artboards the camera would jump from canvas to canvas while being zoomed in a ton, thus disorienting the viewer.
- If you disabled the camera following your brush strokes it would record every Artboard at the same time, thus making everything look small (no way to direct the camera or decide the zoom level).
- There was no way of cutting stuff out in the timeline to decide where you wanted to start or stop recording. It only recorded the entire timeline and this was a big problem if you had literally thousands of history states to record from. Since you couldn't preview the results of your recording, you would have to wait for the recording to finish completely to have an idea if it was better or worse in quality.
- No way to cancel the rendering of a video in a simple way. Once you hit that record button, the entire program started to freeze and you would have to wait.
- It was very unstable and crashed a lot.
- Rendering took very long to finish, even if the document was very simple like line art on a single layer.
So yeah, it was removed for a good reason. Hopefully they revisit the idea someday since it is indeed pretty cool to have, but it has to address the problems it had before it should be even considered for an official release.
Here is also a recording I made using the feature with the best settings that were available:

Fair enough... However, I insist to highlight this capability is required and will be highly appreciated when available

I’d love to see a Timelapse fracture added to Affinity’s Designer (on iPad). Similar to how Procreate and Vectornator record a timelapse while you work. Then when you have finished the project, even over several sessions, you can view the timelapse of all you’re hard work, and even export it as a video.

After trying out procreate recently, I found the timelapse export feature to be a nice feature. I see from research that this functionality was once in a few betas of affinity apps, but got dropped. Here’s an official request that it be put back on the table, but with the ability to trim and possibly set speed of the video before export. Thanks 

Export Timelapse feature +1
A very useful feature. Hope it's ready sooner rather than later!
