Mee too, my main issue is in Bluetooth mode, it stops sync within minute of playing a song, goes mute or de-syncs. I'm going to try reinstalling the app and or probably resetting iPhone to factory but with all the complaints here I feel this won't solve my problem.
After chatting with support, this is my fix: log out and log back in ( if you haven’t reboot your device in a while, do that first). I can’t believe that worked but I’m glad I didn’t have to reset my iPhone to factory, that’s a pain in the **bleep**. Anywho cheers! :) Musica is Lyfe!!!!!!!
