Hello @dlazic 

Have something changed in your environment?

Have you tried to test that all approval fails - try it out with yourself?

Kind regards, John

Thank you for responding. We were able to figure this out with Microsoft tech support. It turned out to be that this particular user was listed as Disabled in Power Automate Admin Center.


To review and resolve, do the following:

  1. Go to Power Automate
  2. Go to Admin Center (
  3. Click on your environment 
  4. Click on Security
  5. Click on "list of users" link
  6. On top left under the pin drop down select "Disabled Users:
  7. See if your user is in the Disabled Users list.
  8. Review users permissions by selecting the users and clicking on Manage Roles
  9. Navigate to Office 365 Admin center
  10. Click on Users - Active Users
  11. Search for the affected user
  12. Review Manage Product Licenses
  13. Ensure that user has Microsoft Power Automate Free checked
  14. Check the behavior 

Hope this helps someone
