Guest users cannot log in into Teams on iOS devices
Our Guest users cannot log in into Teams on some iOS devices, however on Android the same account works perfectly. We tried different ideas and on some iOS devices access is given, on some not. It doesn't depend on IOS version.
Error message: Your license doesn't include access to Microsoft Teams, please contact your Admin

Please fix this bug. On Android guests can log into Teams if they first log in on the Teams web app. But on iOS browsers (both Safari and Edge), the link to join a team takes user to the app, and there is no option to open the Teams web app, even if they request desktop site. Requesting desktop site doesn't take them to desktop site (except on older devices like iPhone 5S). Even if users first log into Teams web app on desktop and then try to log into guest account in iOS app it doesn't work (see error message attached).
