Problems loading AppInventor

My students have been having a lot of trouble loading the platform. They can spend 30 to 40 minutes trying to open App Inventor. Is anyone else having this problem?

No problems here.

What URL do they use?

https://ai2.appinventor.mit.edu/?autoload=false

?

Assuming a school network environment, have your IT team been advised / changed anything ?

Can you, as teacher, connect to Appinventor OK?
