I can confirm that the issue is still present in the most recent update.
I have recently come back to iPhone after a year break on Android. I have to say this is the worst update EVER! my phone hangs all the time, the screen flips at will, reception drops and comes back straight away, iMessage isn't working properly and now the sound!
COME ON Apple! I came back because I had faith that the device would work and not be so 'clunky' as with Android! Apple music seems to have broken my phone too...for a fee which is nice!.
I can't be force closing apps and fiddling with track times when driving so FIX THE AUDIO ISSUE NOW please!
I left Apple for a number of reasons, one of them being due to a documentary on their sourcing of Tin. I came back as Android is clunky but in all honesty I am regretting my decision. Please don't ruin your rep of having a stable OS! As is now, Android may be clunky but now so is iOS! If im going to have a clunky OS then I may aswell go Android and have a waterproof phone that actually plays music! GoogleMusic also doesn't hang when playing offline files when not connected to the internet!
Bad show Apple!
