Not sure if it's real or just coincidence, but Spotify for me went from completely unusable (not managed to get a single tune out of it on the drive down to Plymouth despite several manual reboots and some spontaneous) to somewhat working (one spontaneous reboot, one period of silence until car parked/restarted) on the return journey - when I switched from using a private Spotify account back to using the Tesla account.
Does this match with what other people are seeing?
