I've moved this to the Windows Central for Windows Phone App Support forum.
Have you submitted a bug report via the app?
Hopefully it was a temporary bug that fixed itself. Please let us know if it plays up again.When I pressed the button it just brought me back into the app. I always send bug reports, I didnt get the option this time. Seems to be running better (normal) now. I just restarted the app twice and back up and running. Cool about the move of thread.
