The radio search function has disappeared from the left hand side, it is available in my your music section but limited to what i was listening too before disappearing.
I have cleared the cache etc, un-installed/reinstalled 4 times, changed password, logged in and out 30 times, rebooted phone including removing the battery.
It only happened after I accepted the free 30 day trial.
I am not logging in through facebook, and the laptop is not experiencing the same problem.
I am using a Galaxy S5
