If i enter the pairing screen from the world selection part (after the initial log in but before clicking ride) once i have made my selection and try and go back to the main screen whichever button I press a pairing screen pops up that has nothing in it making it impossible to exited the pairing section.
The only way I have found to get round this is to hold the stop button on the companion app.
Not sure I explained that too well but it is quite hard to describe.
this is on the windows version.
