Youtube recently (as in last week) has been fuckin around with stuff to try and kill adblockers again, which means basically anyone using nonstandard browsers, VPNs, pihole/adguard dns, etc are having issues. Even some people who are using legit clients but just have an old oauth token (like phone users who logged in 2 years ago)
google will inconvenience 70% of their user base to kill adblockers (temporarily, bc I’ve already gotten ytplus working again without even needing a new build ha)
