Moon+ Reader pro

[pgibby]

Hi. I've recently switched over from using Google play Books to moon+ reader pro as it just gives me a lot more flexibility as regards annotations, book covers, tagging and several other things. At present thinking individual books between my devices works very well - Pixel 6, Tab S6 & Boox Ereader. However, my problem is how do I get my bookshelf to sync between devices? One of my main reading devices is the tab S6 and that shows all of my books in the bookshelf. My other devices only show most recently opened. My question is there for how do I sync the bookshelf between devices? Thanks for any help you can give! I'm using Google Drive by the way.
