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.
I’ve had the extension for a years and basically forgot about it but boy was it eye opening to see all the blocked requests it throws on adguard home. Not as bad as microsoft trying phone home but it’s noticeable. (I’ve since removed it)
