My solution to this current Apple Music and Email Link Mess
Hello.
I would first like to thank the person that posted the "log in log out" solution. sorry i don't have the link but to help out as many people as possible I am creating a post that SOLVED my project (for the past 1.5 days at least. so far so good.)
I too was suffering from the apple music not playing, settings for music getting "stuck" and email links not working in apple email problems on my iPhone.
I recently updated to 8.4.1 and while the bug may not be in that, i believe when one updates something is checked or changed in your apple ID record back on apple servers. Sometimes this gets corrupted or out of date. Note. I only experienced the problem on my iPhone but that may be because i used my iPhone 95% of the time this past week.
I use apple music in my car and as you know, apple music radio would not work, songs would stop playing after 3 or 4 songs. i blamed my car.
Needless to say, this drove me crazy and to this forum.
Here is how it fix MY devices of the problems a lot of people are having on this forum:
1) find all your iDevices (iPhones and iPads. all of them. including ones you have not logged into for a while)
2) Go to your mac.
3) Open iTunes
4) log out of your iTunes account.
5) for each of your iPhones and iPads (leave your iPhone for last.) :
a) go to settings
b) go to iTunes and app store
c) sign out.
d) make sure you signed out. (your password field will be blank)
e) reboot device
f0 go back to settings -> iTunes and app store AND MAKE SURE YOU SIGNED OUT. (one of my devices took two sign outs and reboots to sign out)
6) go to settings on your iPhone
7) turn off iCloud music syncing? on your iPhone. this may require you to reboot phone, and then go to settings ... iCloud music
8) Go to settings -. iTunes and app store
9) sign out
10) reboot your iphone
11) start using apple music again. (note your playlists and some music may be gone.)
12) once apple music is working again, you can turn on iCloud music again to get your other music and playlists.
I believe all our problems stem from a corrupted apple ID record that gets "stuck" between apps and devices.
I hope this helps others.
