App freezing when Duplicate function in use

I’m making some tests for the upcoming show and after the last updating my iPad, have experienced some strange freezing of app, when the Duplicate function used.
If there’s one image it freezes for about half a minute, if there is several layers group it can take about 3-5 minutes, then the app gets back to normal.
Have anybody experienced the issue?

Nothing like that I have experienced beforehand

Looks like the layer you want to duplicate is very large and needs a lot of memory.
A lot of painting strokes in the same layer can be very intense for the iPad.

Maybe a screenshot of the layer is less pain.


Ok, Thanks
