Same for me, first noticed it last night when I turned the box on. Never had the issue previously. I'm on Plusnet internet now with a third party router.

and type in YVM502, and not any incorrect version of this error code.
It just says restart your box & router which don't fix the issue
And concludes:-
If you're still having a problem then contact the TV Helpdesk >
Have you done this? Though you may now need to wait until 7am to talk to them 😢
Strangely it seems to be fixed now. 😄 Many thanks for your reply!
Nope, I turned the box off at the power and back on about 9 hours ago but it had been on standby since then. I turned it on and didn't even notice it had gone for about 20 mins. One thing I'd noticed last night when I had the message was the featured apps row had shrunk a little bit. But now the message has gone and the featured apps row is back the size it used to be. So I'm wondering if the software has been rolled back or something.
Hi, glad to hear things are now working as expected. We believe the issue was partially due to a Youview change on the 26th November that (depending on some other factors) meant that the top app rail was not populated although the underlying apps remained fully functional. That change was reverted last night and we've confirmed service has been restored for the affected boxes. If you are on a BT/EE box and still see the issue, a quick reboot should fix stuff.
Sorry for the blip.
Cheers
David
