When ONLY EPUB files are opened with NeoReader 2 (firmware 1.8.3_9269185), after many power off/power on cycles, the last file or when a new EPUB file is opened, the display is done in fullscreen mode without a way to have access to the previous files.
But if a PDF files is opened, the multitab tools is present and you can have access to the previous EPUB files opened.
It’s seems that the Note have the same problem.
The problem is shown on the pictures.
Thank you by advance for your help.!
