Autocomplete and 'Complete and Continue' not working

Neither the autocomplete, not the manual ‘Complete and Continue’ are working. Both lead to the same video being replayed instead of going to the next one. I’m also unable to complete videos, so I’m still at 0% completion, even though I already watched a bunch of videos.

It was working for me yesterday on Chrome (Android). What browser / device are you using?

Are you using an adblocker or anything preventing cookies / local session to work properly ?

I tried chrome, edge and firefox on win 10.
I’m not using an adblocker and cookies are allowed.

Edit: It’s working on my laptop, so I guess there’s something wrong with my PC settings

As the old adage goes: “have you tried turning it off and turning it back on again?”
