Dear Affinity Designer development team,
I'm taking the time out of my day to write because I believe in small smart teams like you trying to make good tools.
I know this is an old topic, but I just want to say this feature is essential to me as a working designer.
I downloaded the trial, fired up, and this is literally the first thing I tried. Finding it not working as expected, I googled "affinity designer move mask layer" and found this thread.
Believe me, I'd love nothing more than to dump Creative Cloud, but I cannot use Affinity Designer until basics like this are ready. Integration with your other tools is of secondary importance.
I encourage you to spend more time getting to know your users and prioritizing their needs.
Thank you!
