Title says it all. Got the message of three remaining videos and then it locked.
I am using FireFox
Edit: Apparently, it was caused by me being logged into YouTube. But I would really like to be. Because that's where all my subscriptions are. If anyone knows of a way to have it both ways, please let me know.
Edit' : It was my Ghostery extension that was causing ruckus. I don't really like the idea of having to switch it off but at least it's nice to know the cause. Anyway, everything is working now. Even when I am logged in ^^
Also to anyone reading this, keep clearing your cache and update in UBlock Origin!
Had no issues on firefox but the popup showed up in brave.
Simply switching off brave shields on YouTube, installing ubo, purging then updating fixed it all up.
