Hi again all,
I'm yet again going to have to reset I think. My ambient Google photos have stopped showing again. And I cannot cast YT any longer.
And I've only just noticed there's two reset options. But I think they are the danger thing?
Freeview Play Preference > Factory Reset
and
Device Preference > Reset
Both end up on the same confirmation screen:
This will erase all data from your device's internal storage, including: your Google Account, system and app data and settings and downloaded apps.
