Cannot Edit Apps -- "Access denied by a security policy established by the Google Apps administrator"

[Tom_Graham]

Noticed I could not login and edit apps on a particular computer last week. Changing computers resolved the issue and I could log in.

All of a sudden today, I experienced the same issue on the computer that previously was working fine.
I was logged in with the same account this morning and was editing apps fine. Just now, when I went to try to edit a different app to the one I had open for editing, I got the login request and then the login error.

We have not made any changes in Google Apps admin.

Does anyone know how to resolve this issue.
We urgently need assistance to resolve this so I can log in and edit the apps.

Thanks,
Tom

Try to open the app with a incognito and see what happens.
