I have a trial Dynamics 365 Portal for Employee Self-Service. I am also seeing this issue in my real Office 365/Dynamics 365 instance.
For my first Admin user I was able to log into the Portal, add them to the Administrator web role, log in again and see the 'Content Editor Tool' floating in the top right corner. All good.
For a second Admin user I do exactly the same thing... but no 'Content Editor Tool' appears. I have tried to match both the first Admin account and the second Admin account exactly the same but nothing happens. I have also Restarted the Portal from the Admin center and have turned the Portal off and on again.
Is there anyway I can diagnose why this second Admin is not working?
