@YouTube
I can't log in to my account on chrome while it works when in incognito mode (chrome) or using another browser? Cookies are on btw, I just get the message: there was an issue signing in to YT. Troubleshoot here but the "here" is not helping either.
Hmm, are you still getting the same error message after clearing your cache & cookies? Here's how: https://yt.be/help/Cko1 . You can also try closing & reopening your browser. Lastly, please check if there's an update available for your browser. Hope this gets resolved.
