I access now tv on my samsung tv through a BT you view box. Every time i access the app on the smart tv - now tv defaults to logged in status under a n account with my name followed by 18. I know nothing about this account and have never subscribed to it. So i have to go through the awkward process of logging out and logging in again with mt email address account to which i subscribe to now tv. This poblem only started happening recently. in the past the now tv app stayed logged in to the last user ie my subscribed account. Even if lofgged into my subscribed account - if i change channels for a second i am again defaulted to the weird myname 18 account. bt say they have had nothing to do with setting up a myname18 account and suggested I contacted now tv. I now realise it is impossible to contact now tv
You’ve said you access through the NOW app on the smart TV but also that you use it through your BT YouView box.
Do you have the native app on the Samsung TV and that’s what you use?
Or do you use NOW through the BT YouView box only?
If so is your billing through BT for NOW?
Sounds more like an issue with the app on the BT YouView box.
Try and do a factory reset to the box.
