Hi @Mary Whitten ,
"Everyone except external users": When you add a new user in Office 365, The user becomes a member of the “Everyone except external users” group automatically, which is granted with member permissions of the site by default.
Since we can't reproduce your situation, we need to narrow down the problem and try some things.
1.Please check whether the user with "You have to request permission to view this page" error has permission in the page permission (the steps are as follows):
2.Remove "everyone except external users" and re-add the "everyone except external users" permission in Site permission and Page permisson to check whether the result changes.
