Microsoft Teams does not completely load
I'm running FirewareOS v12.1.1 on a cluster of two 850's.
When a class of about 30 students go to Microsoft Teams (teams.microsoft.com) the page does not completely load with most of them. Other sites work without problems. The menu / framework is loaded, but the real contents (like the assignment) on the page won't load. I suspect the proxy to be the problem in this. So I opened the HTTPS-proxy and changed the connected Webblocker config. I added an exception to Allow teams.microsoft.com/* (also with a * in front, but in this forum it gives me bold font and both the stars dissapear, so I could not add that here), but it did not solve the problem.
Where else can I have a look or change a setting to have Teams completely load the page?
