I also received the email from ITV HUB informing us that our 7 year old Samsung SMART TV would no longer receive ITV HUB after 22 September.
I also feel that this is wrong, particularly at this time. Not everyone can afford to replace these things.
We consulted our local independent TV shop, where we bought the Samsung, and were pointed in the direction of an A****N firestick .. comes with a remote, slots into the back of the TV and should enable ITV HUB.
I believe it basically gives a standard TV "smart" function.
We await a visit from the shop to help us with installation.
Now I discover the same has happened with our BT TV box used with the TV in another room. Wonder if we need to get a new BTTV box ....
I find all this stuff so draining.
