@gomezz TNT Sports catch up will not be available in any EE TV apps on any platform. It will be available in HBO Max on all of their platforms.
As far as I'm aware, the replacement box is free of charge to customers with a current subscription. I've asked for confirmation that there are no admin or delivery charges on it - I would assume not, if it doesn't mention in the SMS.
Thanks for checking that for me.
It is all moot now as EETV no longer has TNT Sports coverage on it so HBO Max it is for the foreseeable.
(pending merger / takeover)
EE TV still has live TNT Sports coverage - just not replays or catch up anymore. For your use though - I agree, it's no longer useful.
