Not sure if it’d work on Netflix but my wife were pleasantly surprised to A&E and History apps on our apple tv suddenly forgetting how to do ads after I set up adguard home with a few extra filter lists…I did have to ok a few things the list blocked. But the apps work and seem to be adless, at least for now.
Perfect time to move to Vivaldi, Brave, Librewolf, etc etc that wont be following suit. (yes the list does also include Firefox…but they bought an ad company and in my opinion are now compromised)
