I updated to 9.2.1 the other day on my 5S and since then I have been having issues with music. Mainly skip tracks a couple of times it becomes unresponsive after a few moments all closes and I get a respring. May or may not be related but I am now having a similar issue with Audible, if I pause it and then hit play it jumps all over the place, it doesn't save position. I have had issues like this on Android and the issue was running out of RAM. I never had these issues until I updated to 9.2.1, anyone any ideas?
