With every update Opera resets some settings in the advertisement section lately.
So all the exceptions for the adblocker were removed, after I started Opera again. Same with "continue shopping" and "booking.com" on the start page settings.
Well, the problem here is, I deactivate them anyway. Why are you urging me to detoggle them?
I wonder if this is meant for those, who don't know how to do this. But otherwise I don't see any sense in it.
