A couple things work like chat and video but when you get down to settings, major things don't work. I've used the Chrome browser version (extremely slow) and the desktop version, which is slightly faster, and used it on the Edge browser (normal) but I still cannot update any of my users designations and I cannot change the host (my website) domain because I put in a personal email, which I used for freelancing so now my website is apparently outlook.com. I watched the settings video and all they do is click on sidebar menu buttons, which I could do myself. I bought a full stack and if this doesn't get handled pretty quickly, I will be forced to put in a refund.
