iOS 10 used all my data plan

[MatiasAR]

Last night I updated to iOS 10 and in matter of hours - I noticed it this morning - it used 4gigs of data of my plan. I'm still trying to figure out what is causing this.
Something has changed, and somehow it is overriding all my previous settings to use WiFi for media sync.

Anyone has noticed the same?

Go to Settings->Cellular, and try to find the app/service responsible.

Well....looks like Google Photos is unleashed, feeding on my data plan like crazy. It must be a bug and the only way to stop it is by turning off data connection for the app from the setting you mentioned
