Hi @matt howell,
Thanks for your detailed case description. I completely understand the situation and your feelings.
Based on your detailed case description and the research we have done, we have found that some of the users in the forums who are experiencing the same issue have reacted that it seems that Power Automate doesn't support auto-update SSO.
However, due to the lack of relevant information about Power Automate in our SharePoint group, there is no official documentation to support this conclusion for the time being.
If the issue is causing significant impact, we recommend you to open a ticket and ask for it.
Please accept my sincerely apologize for any in convenience this may cause. Thank you for your kind understanding.
