Ok. Just keep in mind that swatches and other color controls will look different when active document is CMYK, and when is sRGB.
I mean they will use color profile from document.

Thanks, i will try to fix it asap

Thanks for this hint, i will do researches asap

We will try to fix all that asap

To copy stamps long press the stamp image and pick "Copy" or "Copy Image to Clipboard"

Lens Blur - i will consider that in the future

File Information - i agree, we will add it soon

Merging mask with clipping mask - we reproduced and fixed that

Exporting adjustment layers to psd - photoshop adjustment layers are not 100% compatible with artstudio so we don't export them at all actually

I did exactly the same test as on your video, and it worked fine.
Does it happen also when modifying small simple documents (just a 1-2 layers)?
Can you reboot and try again?
If it still happens -  Could you send me the document from video?

Can anybody confirm that issue?

I cannot reproduce this, it just works fine on my iPad with iPadOS 16.4.

If you know how to repeat the issue please send us all steps.

update:

I reproduced the issue on one of my iPads, and fixed it!

Thanks for your feedback!
