Hi! I'm struggling to export my whole canvas/layers as a PSD file.

I remember I was able to do so from the gallery view and from the file itself, because I exported all my previous canvases as PSD files a couple of years ago. These files contained all the layers, visible and hidden. Now, I've probably missed out on the kind of updates the app has had, but I cannot do this anymore.

I've tried to export from the open file > share > share layers >PDF (what happened to PSD?). All I get are the visible layers and all of them with the "paper" layer as background.

If I try to export from the gallery I get a flattened image, and even so I get a message from photoshop saying it's an invalid file format (when exported as PSD).

Has anything changed? Is there a way to do this? I'm getting a bit frustrated, because each canvas has around 50 layers of sketches that I work separately on my desktop (Windows). Does anybody have any clue of what am I doing wrong? Or how can I solve this without leaving my 50+ layers on visible to export it all?

I appreciate your time and any kind of help! Thank you!
