When students try to put class code in it takes them back to log in page and no other way allows them to log in

My students have been unable to start on cospaces because they cannot log in. When they put the class code in it brings them back to the login page. When they try to log in using google accounts, it says there is an error and to try again later.

Just a heads up they are using the app on ipads.

I think there is a bug for Google log-in on mobile devices.
