MobileSheetsPro cannot currently override the OS settings in the Boox Max (Onyx is considering adding support for apps to override it though). You need to go into the BOOX settings and find the timeout for the screen and increase it to whatever value you want. That will prevent the tablet from going into standby mode.

Ok

Thank you mike, 
As it works on my Asus tablet and i didn't remember to have test it before on the Boox Max, i was thinking this issue was related to the last update of MSP.

I will increase the time out when i  would use MSP.
