Cant see those who join and they can't see me?

I have a friend that is trying to watch some youtube with me, i’ve never had an issue with this website before but recently it’s just plain not working. I can send them the invite, they join but i dont see it. I need to refresh the page but even then it says they are offline, which isn’t true, and when they send a message I don’t receive anything. What’s going on???

I’ve never had any issues before until now.

Hi… can you send a link to your room to I’ll have a look then. Please make sure that both of you clear your browser caches as well. There were some larger updates recently and it could be that you are running on an older version. - Florian
