i‘am also evaluating affinity foto on my new ipad pro 11 with ios 12.1.
I run into the same issue...
as iam new to affinity photo, it is very hard to seperato my faults from issues like these.
iam a little bit disapointed because i bought the new ipad especially for learning affinity foto. So i spend very very lot euros.
Does it make sense to go back to ios 12 instead of 12.1 ?
can you provide a estimated schedule for a bug fix release?
Is there a bug tracking tool, where i can enter the issue? If it helps to get the things working, i would help ;-)
with best regards
