I can access to all my comics and books in the quest but when I enter one after the first 2 pages it keeps buffering forever. So I tried to transfer my files with the usb method but it keeps saying "Connect you headset". I tried dev mode on/off and cnnecting the headset in different moments but nothing worked.

The feature comics are awesome but I want to read my own things :(

Also the epubs crash the app after buffering for 2 sec

Are you scrolling from page to page or clicking next page button?  I have found that scrolling produces the buffering thing but next page does not. 

Thanks, but I tried both but nop. I read that you need a good pc to read on the cloud and mine is super shitty, I really need the usb transfer mode. Hope the dev isnt dead.
