Just a thought on this, but perhaps it was a Spotify issue all along...
My thinking is that if it was a Volvo issue then the only way that they could fix it would be to issue an updated software package to replace the one that wouldn't work. Doing so would presumably result in everyone receiving a software update notification....something that I've seen no mention of between the issue first appearing and it resolving itself earlier this week. The fact that we haven't had swathes of people saying that they've had to do an additional update would suggest to me that the fix has instead been completed in the back end, i.e. by Spotify.
Obviously I've no facts to back this up (but when has that ever stopped anyone from sharing their theory in a forum, lol), but it does seem quite logical to me. Anyone share my thinking (or want to suggest an alternative answer
)?
