Is your account with BT or EE?
If you are an EE customer, you need to post on the EE forum https://community.ee.co.uk/
EE are a separate company within the BT Group.
All a bit murky really - the router has BT on it, the box the kit came in has BT on it but the remote has an EE logo as the on/off button. As far as I'm aware, I'm a BT customer but who knows!
Did you setup a BT ID or an EE ID, when you placed your order?
Or https://my.bt.com/appsconsumeraccount/secure/dashboard.do
BT
That is a bit odd if BT are trying to get new customers onto EE?
You are on the right forum, so hopefully one of the forum members can help, as I do not have a TV account.
AFAIK there is no way to add it remove apps from BT or EETV.
Alas, you can’t remove or hide them 😢
But you should investigate Parental Controls on BT or EE, once you have clarified whose broadband you have.
Thanks everyone for your input, much appreciated. Hiding the remote may be the order of the day.....
