I can add a local photo or file (in the apple files app) and an image (jpeg) from LR, but I cannot mege another PS file into another. The files are not saved locally (and thus unavailble via files) and filetered out of LR view (because they are PS files)
There is no easy was to copy a layer/selection on IOS
This is part of my workflow if my camera images require transparancy in post production.
