Please disregard this post. I just realized that i was triggering Develop action by doubletapping on Apple pencil. Sorry for this submission.
System info (in case it's helpful):
11'' iPad Pro, iPadOS 13.1.2
Affinity Photo 1.7.3.155
I fairly often encounter situation when Affinity Photo will develop RAW image (in Develop Persona) without me actually clicking the "Develop" button. At first I thought that I was somehow accidentally triggering development by holding iPad by the edge near the "Develop" button, but then i saw this occur even when iPad was laid on the table and I was not touching it at all. I had this thing happen to me even when I was using cropping tool, when there isn't even "Develop" button to click.
