Heya - so random buttons have stopped working on my A4 including all the white note buttons 
not sure how it happened, it’s been in storage a while and shouldn’t have been damaged, guess it could have been!
I’m crestfallen really, I can’t access the global menu to enable overbridge and control it remotely.
I was wondering if anyone had any ideas about how to enable overbridge remotely? Ive tried reinstalling 1.40A and a factory reset, hasn’t helped sadly.
