I have installed Moon Reader Pro on my ONYX BOOX MAX 3. Got message while run and setup Moon Reader The reader needs Storage Permission to manage book files. After allowing this permission I got another message:
Screen overlay detected
To change this permission setting, you first have to turn off the screen overlay from Settings>Apps
Open Settings
After opining settings I got list of applications, but there is no Moon Reader in the list. Without this perdition it is not possible even reed books. How to solve this problem?
