Thank you for appreciating your reply.
Yes, I agree and am familiar with this process and you are correct "When a new response is submitted".
I think there is a major issue as all my flows were working correctly at the beginning of the week and now all have stopped.
To help target the issue once the " new responds is submitted " I would used to get notifications of new "Updates" fulfilled and thanks to flow executed notification on "Approvals" cycle submitted.
I have checked status of "my connection in use " also "manage connections" everything is green on approvals, forms, outlook, office 365 users and finally planner.
The symptoms are: we do get the "Updates" submitted but the flow isn't initiating.
To help trouble shoot I rebuilt a new "Update" Form (thus recreating a new "Form Id") tested and failed also I did a save as of the flow and then retested and failed.
I have at least 40+ "Updates" Forms with 35 Flows on power automate. I am baffled, please help.
