I sent in a few crash reports when the app asked.
Affinity Photo Beta 1.8.2.174
iOS 13.3.1
iPad model MLQ62LL/A
I was simply importing some Canon EOS 5D Mark III raw files (.CR2) from cloud storage (OneDrive) to develop and convert into JPEG. The goal is quick, simple, and one I've done countless times without any problem whatsoever for years with Affinity Photo on iPad.
However, with this latest beta, MOST times when I tap "Import From Cloud" and select the file I need, I get a dark screen with the usual spinning/thinking animation. But instead of the words "Importing" it says "Downloading". Each and every time it says "Downloading" I know within a few seconds the app will crash. Every time it says "importing" the file opens normally, and I can work and then save the image normally.
As it is now, it is practically unusable for this simple operation. I have not yet had the chance to test with any other cloud storage service. Let me know if I can supply any other info or hints that might help.
