[Save/Export Locations Greyed Out]

@Dan C , thanks for your response!

I am using Affinity Photo for iPad. It would seem the issue has been resolved. 
My iPad Pro automatically updated from iOS 11.4. to 11.4.1 last night and it has resolved the issue.
I can now save normally by selecting a path through the export menu anywhere on my iPad, as well as using the drag method you described.

Since this is an unseen issue, if you'd like me to roll my iPad back to 11.4 to test further, let me know. It would be no problem.

@omalleyfr sorry to hear about that, I empathize. I'm mostly a Windows/Linux guy where there's endless documentation and forums posts with solutions. 
In my time using Apple devices more and more recently, I've found a lot of issues like this go unanswered by Apple and unsolved as a result.
I don't know if its related at all to my issue with the iPad and iOS, but perhaps if there's any updates you can do, that solved it on my iPad.

[Save/Export Locations Greyed Out]

Hey all,

I’m unable to save/export any of my images from Affinity Photo to my iPad. The location options are all greyed out as you can see in the attached screenshot.

Any advice? Thanks!
