Im not sure what to call this but the formating is weird on my tab s8 +. (Screenshot attached.) I can see part of the previous page. I know it may be just an aspect ratio difference between a Samsung device and an iPad, but I don't remember this being an issue on the ios version. It would make the experience nicer if you could see just the single page. I tried changing from the "goodnotes standard" template to letter size but I could still see the previous page.
The attached screenshot is with my tablet in portrait mode, my preferred way of taking notes. The black bar above is the selected cover of the notebook.
