That's definitely not normal... MobileSheets should remember the input and output ports that were selected, and if those are detected at startup, MobileSheets should connect to them automatically. If you restart the application and go to Settings->MIDI Settings->Configure MIDI Connections, do the input and output ports show as connected? If not, MobileSheets may be encountering some kind of error while trying to save the MIDI port information. In that case, you can go to Settings->Backup and Restore->Export Settings and send me the settings file and I can try to repair it, or you can go to Settings->Other Settings->Reset Settings to Default if you don't mind having all of the application settings reset. This is just a guess though as I can't think of any other reason MobileSheets wouldn't be connecting to the ports you selected.
