Without knowing more, it sounds like the some of the MIDI identifiers are changing every time you reboot your device, so MobileSheets doesn't automatically connect (requiring you to go check the 4 boxes again). If that's what is happening, that's definitely problematic, and very strange, as USB device identifiers don't typically change like that. It would be really helpful if you can try a few things for me. First, try going to C:\Users\<your username>\AppData\Local\Packages\41730Zubersoft.MobileSheets_ys1c8ct2g6ypr\LocalState, open the defaults.xml file and delete the default_midi_input_ids and default_midi_output_ids entries. If this is overly complex, just send the file to mike@zubersoft.com and I'll update it for you. This will clear out any saved MIDI devices in the settings. I then want you to go through the testing again to see if there is any change. If not, it might be a good idea to backup all your application data (copy the LocalState folder somewhere safe), then uninstall, reinstall and put the LocalState folder contents back. I just want to know if this has any impact on the MIDI connection.
