Thanks for the update, Chippy.
Tapping the power button? It seems that the devices tend to lock themselves or fall in sleep mode after the auto-update. Will deliver this message to our team and see if they have a clue.
We are trying not to roll out updates too often unless there are serious defections of current version or new features to present in the next version. We want to make sure you have a better experience every time.
Although we have done many tests before the official release of a new version, we may still have unexpected situations with each update. This is why we encourage users to report back to us as soon as they encounter any problem.
