Netflix incompatable on Smart TV not even 2 years old.

We Bought x4 JVC Smart 32inc TV in August 2023 and about two weeks ago my tv said that Netflix is not compatible with the tv's. All we do is watch Netflix on them. Now it seems like a wast of money. We bought these TV's at Checkers Baywest PE on special. Now i know why these TV's was on special to get them out before this happens. I cant believe that a smart TV apps can stop working. So please make sure before you buy.
