I think we figured it out, at least for our situation. This particular
user was using the instructions given for the windows client. For the
windows client, you can include the port in the HOST URL line, so

one user on an iPhone 11. My iPhone 13 works fine. Hoping someone has a
fix. It seems like the Office365 login page just isn't rendering in the
browser that pops up. All you see ...
