Constant Buffering and occasionaly black screens

Hello, Ive been using watch2gether for a while now and lately my girlfriend has been having trouble with the videos buffering a lot. I thought it could be internet connection but it seems to be working fine in my computer in a connection that is worse. Any suggestions are welcome. Thank you for your time.

We rolled out an update this week that could improve this. Do you have a chance to try it out?
