Hey @TeamYouTube can't log in on my YouTube app (iPhone). I can sign in, use my 2 factor authentication and it reverts to the same before like I never did anything. Already have latest app update, tried restarting phone, deleting and re-adding app mult. times.
Thanks for sharing this with us. Mind sharing a screenshot or a short clip of this? Also, can you check if this is happening on other mobile devices or browsers? Keep us posted.
