Hi Komal Kumbhar.
When I opened the workflow builder appears an info message saying the app was updated, so is possible some changes happening.
On my side is working as expected, but I tested with the sample users that were created automatically. I don't have the users configured yet.
One thing that I notest it took some time to update the list of the supervisor (in my use case), but working as expected.
Regards
