Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Dear mj78CA,
Good day! Thank you for posting to Microsoft Community. We are happy to help you
I want to confirm if this phenomenon occurs in multiple browsers?
If this phenomenon occurs in multiple browsers, and you mention that multiple users in your organization are experiencing this problem.
Since this phenomenon is mainly caused by the slow loading of the application service on the web side, there may be a problem on the server side. And if you confirm that the browser is not causing this phenomenon, we recommend you can raise a service request in Microsoft 365 admin center, which the support there has the related permission and resource to help you check from the backend. They can assist you with such issues regarding the tenant server side.
Thanks for your cooperation.
Sincerely,
