I have 3 different flow that had some instances in the "Running" state. Less than 100 combined "running" items. I used the "Cancel all flow runs" button in make.powerapps.com, where it said it may take several seconds, up to several hours, to cancel running flows depending on how many of them there are. Several hours later, all the flow instances are stuck in the "Canceling" state. Even if it was taking 1 minute per cancel, it should have been done by now. Plus I would have expected to see SOME of the items with status "Cancelled" as they were cancelled but this obviously isn't the case.
Th problem - it looks like having the flows stuck canceling is blocking the flow from triggering (trigger is a row created in a dataverse table). I can manually "test run" the flow, but the trigger itself doesn't fire when items are created. I've tried turning flows off and back on, etc, but flow still doesn't trigger.
Any suggestions how to fix the problem?
