Anyone else having issues with @YouTube recently where everytime they click the tabs on the left side (ie: subscriptions, history, etc) it signs you out and when you sign back it, it gives a 404 error?
Tested on other devices, it seems to be just on Chrome I'm having this issue. The troubleshooting guide you provided is irrelevant as this issue has been happening for a few days now. I will try manually updating Chrome, see if that sorts it
