It wouldn’t let me in, I got the countdown screen but the viewing website wouldn’t load

Couldn't even see the movie. The link didn't work looked like the site crashed. If you're going to do a screening and you send invites to everybody, be prepared for a lot of traffic. After several tries it didn't play for me because it said another device was already playing it. That was not the case, I was using the same PC to open it. Terrible experience, didn't get to see the movie.

could not get connected to streaming.

I could not watch it. Link did not work.
