Pathetic!

I have subscribed to Disney + and was able to watch using my existing TV box up until this week when some sort of update was run on the Disney system and now I cannot access the Disney + app at all. I have been to the Disney + website and have used the chat only to be told that my TV box is no longer compatible with the update. What absolute nonsense is this, so now I am unable to view something that I have paid for in full and if I want to view Disney+ I have to go out and but a new TV box, what kind of a software update does that???? This is abysmal, I'd appreciate some solid assistance here and not simply be told that I have to buy new devices to view Disney +!!!!!
