I'm just starting with the extension so will let y'all later how it does, but from the start I can share a quick fix for the current yt issues. Details on their github, issue 2692.

The fix is to disable uBlock Origin - quick fixes from the Settings > Filter List > Built-in > uBlock filters

I've no idea why, maybe some of the filters relied on hard-coded paths and yt changed layout. Hopefully they'll fix it soon
