Hi all,
I in fact raised the same question a while, it solved my issue. But when my PowerApps deployment going more massively, and the records size is getting larger. This corresponding flow seems too slow and creates some issues. So I need further help.
I have a Sharepoint List with the following fields:

The Regular Meeting happens nearly everyday, and all members will be joining. In my original design, the user update the record using PowerApps, and a flow triggered by "an item is created or modified" to update the Actual Hours for all members. But issue comes as this will create a ETAG error, ie updating the same record by two sources.
Therefore, I'd like to change the design to delay the update from Flow by using Scheduled as attached:

This filter query works well to narrow down the records for "today" and with a specific title.
In the case that one of any members updated the Actual Minutes by the PowerApp, I'd like to have the Flow to update the Actual Minutes for the other members as scheduled.

How to get the item which has a value in Actual Minutes and update this value into the same field of the other records ?
Thanks,
Gavin
