iPhone music app freezing, throwing me out, misbehaving
This is on an iPhone 6 with the latest iOS 8.4.1 as of today, running the music app with an account for the family. As I'm browsing and listening to music, the app threw me out after an hour or so complaining about an authentication failure, unable to log me in. Quitting and restarting the app didn't work. Getting to the iTunes and app store section was impossible as the settings app would freeze when I pressed this menu item. Rebooting the phone got it working.
I am seeing the app misbehaving at irregular intervals, with the screen just going blank with no music list or albums, but it doesn't stop playing what's already on.
At other times, selecting a song doesn't play it. The app appears to "think" about it for a while and simply gives up. Retrying 4-5 times gets it playing.
There's really no problem with my WiFi or net connection and I'm on a 200Mbps fibre line here. Just to test, spotify worked just fine with no glitches.
Are there any tips & tricks you have used to resolve these problems?
