It does, you just have to purge and then update the filter rules

You are just being lucky. Youtube have been rolling out new adblock filtering globally for the last few weeks.

See https://www.theverge.com/2023/10/31/23940583/youtube-ad-bloc...

This works for me too having my youtube account logged in.

Steps: click the U icon, click the gear, click filter list, click Purge, click Update.

Ads are gone again while logged in. You might have to do it again every now and then.
