Hi @Mike Burns
Thank you for posting this in Microsoft Q&A.
I understand you are facing an issue that myapps.microsoft.com shows a blank page but then you refresh the page, and it works.
Could you please attempt to use a different browser or try using Private/Incognito mode to see if the issue still persists?
Can you try to change the URL by using its full URL: https://myapplications.microsoft.com
Hope this helps. Do let us know if you any further queries.
Thanks,
Navya
