I bought Affinity and my iPad Pro two weeks ago. While in general I think Affinity is good there are many bugs, which make it difficult to use compared to Lightroom mobile (I am a Creative Cloud subscriber).
Affinity crashes far too often.
The Panorama module in Affinity won't accept RAW photos.
And, most annoying, many times when I am in Develope module if I happen to touch the wrong, arbitrary spot on my screen my work is deleted with no history to retrieve it!! It goes into Photo module and the history is blank.
I do not like to waste time when I am charging clients for post-processing.
Luckily I am only testing Affinity.
Please correct these issues or suggest a way to resolve some of them.
