FSE reported few hrs in return travel while completing the task but the entry does not reflect on browser. Any idea why?

Have you checked in the Failed Transactions what is the error? This is most likely due to the difference in time zone of your device and the timezone of IFS cloud server. When I changed the time zone of my system to that of the IFS back end systems, it was resolved but that is not a good solution but we can live with it till a further solution is developed/found.
