Just bought and installed MobileSheets on my Boox Max Lumi2 and, as a backup, also on my cell phone. On the phone it works, but not on the e-reader. When I open the app I see the start page, but nothing works anymore. I have to restart the e-reader to be able to use it again. The trial version that I installed previously still works fine. Any ideas how this problem can be solved?
