Updated my phone to Android v15 UI7 and ever since the widgets have not working. 

Specifically the "On/Off" Control. 

Originally had two separate P110's set up to be able to press "on" or "off", it would buffer and then give me a tick icon and work, turning the device on or off.

Now when I tap the on or off it gives me instant 'red x' symbol and does nothing. 

Have tried removing widgets from phone screen. Removing actions in the app, uninstalling and reinstalled the app.

Nothing is working. 

Help please!
