I'm having the same issue on the same device, also it's always unclear where the next imported image will appear.
Unsure if that is a different issue or the same one.

I think it might be worth considering being able to copy/cut the selection and paste it onto another page. This would work around the ability to drag onto another page, but also make it easier if you want to copy/move something to a page many pages apart from the current page.

I just wanted to add that I recently discovered Saber and it really ticks almost all my boxes, it's really wonderful. Sadly, not being able to move selections to different pages is the only thing holding me from using it for my notes.

I use my (non open-source 😨) note taking app for doing mathematics, to work out and develop new ideas. This is a quite lively process and I need to be able to reorganise my notes once I finally understand what I'm studying, which mostly involve dragging notes around...

@austinliuigi If planning on implementing copy/paste, I request you (or the developer) take a look at the Squid app (Android). Cutting/copying a selection in there copies it to the device clipboard rather than an in-app clipboard.

This behaviour allowed me to paste the selection in a different app altogether. In my workflow, I draw my diagrams on the Squid app (Android), Select it > Copy > Switch to Notion > Paste. Neat Result.

Very few apps have implemented this behaviour (I have tried a lot of them). Another example I can think of with this copy-paste behaviour is Goodnotes on iOS (not very sure about it).

Highly helpful for mixed note-taking.

I have this issue also on all my devices (Samsung Phone, Samsung Tablet, Linux Laptop). I would really like this to be fixed because I need it for things like template grid for functions in mathematics etc.
There is lots of doing the same thing over and over so not being able to copy it to the next page is quite a blocker
