Swiping to browse stops working randomly

[Kindai]

I've had the App a few days and found a bug with regards to swiping from right to left in the now playing screen to reach the browser,  where this function stops working. This has happened twice now, with no apparent reason. This is with the orange button turned off.  I can resolve the issue by going into settings and turning orange button back on and press it. Then swiping works again.

Im using Sony XZ1 Compact with Dragonfly Red.
