I've never signed into Netflix on this blu ray player, I don't even have a subscription. I've only connected the UB820 to wifi to update the firmware, but in adguard I see it is constantly phoning home to Netflix. All of this is exhausting, you're screwed if you're not technical enough to block this sort of spying. This should be illegal.
