Google has been blocking Invidious with error "This helps protect our community"
EDIT by @unixfox: The Invidious team is aware of this issue. It appears that it affects all the software using YouTube. Please refrain from commenting if you have nothing new to bring up. Thank you...
Youtube continue breaking changes which can foil Invidious
Yep. Even my private instance that only I use is affected, Newpipe/Tubular and basically every front end is currently non functional to my knowledge.
