YT are getting shirty! I’ve been getting pop-up notifications from YT saying, experiencing interruptions……find out why. I get a buffering symbol for 10 seconds & sometimes the video just stops for no reason.
When you click on the find out why notification, it says your browser extensions that block ads are affecting video playback. I’ll put up with the minor inconvenience rather than be bombarded with bloody ads.
I’ve been getting that notification for a few months but oddly it’s not appearing at the moment.
Maybe they’ve decided to pick on you and give me a break for a while 
I don’t know much about ad blockers, but had the impression that youtube would still hit you with afs before and during playback regardless, as they understandably have control of the video stream going to you.
A good adblocker will stop those adds
