Someone damaged me, and I lost the inscription "Viewed" on YouTube. How to return?

Question

YouTube

Requires a white magician lvl 90+ to remove the spell.
The browsing history continues to be saved, but there is no mark viewed.
She disappeared about six months ago.
I reinstalled the system about a month ago and still the same.
There is also no label on the phone.
I watch everything from one account, personal, which has been around for many years.
There is no ban, but everything indicates that the problem is in the account.
Tried disabling ad blockers, didn't help. On the phone, by the way, they are not.

Answer 1

And I have disappeared. Now instead of it there is a red strip along the bottom edge of the video. Whoosh!
