I have located the cause of this problem. When I query for available MIDI devices, if a bluetooth MIDI device shows up in the list (meaning it appears in device manager), then I attempt to connect to it using the approach recommended by Microsoft in their documentation. However, if the device is not actually connected, the call to connect hangs forever. So I'm having to make some significant changes to the code I was using to query for available MIDI devices and connect. As a workaround, users experiencing this problem can unpair with the MIDI bluetooth device and remove it from device manager. Then MobileSheets will connect successfully. I'm working on putting together an update right now to fix the issue.
