How do I stop "TuneIn" autoplaying radio when I connect to bluetooth?
Ever since getting an iPhone SE on iOS 14 (previously iPhone 6 on iOS 12) whenever I get in my car, the phone automatically connects to bluetooth, as it should, but then starts playing Heart Radio via "TuneIn". Now, I don't have a TuneIn app installed and never have, and when I tap the "now playing" in control centre it opens the iOS Music app. I've never asked it to do this, never had TuneIn installed, never selected or listened to Heart Radio and I don't live in or near Luton, Beds (which is a place in the UK for those that don't know) so I really have no idea why it's doing it but I'd really love to know how to stop it. Prior to this, it would often start playing either that last app I was using for music (usually the Planet Rock radio app, or the Music app with either the last song playing or it'll start on a random song), which is fine - I'm happy for that to continue. But I don't want whatever this this is.
Any ideas?
