Hi @sunithav ,
Is this a recent issue or has it been bothering you?
Sometimes because of a problem with the SharePoint service, Flow may not be triggered in time.
For reference, my license is a per-user plan, but after my tests, the results on my side are in line with expectations.
Please try to use another list, other Flow environment and update the connection for more tests to see if the results are the same.
Best Regards,
