I'm trying to setup an Approval flow. After the 'Start and wait for an approval (V2)' step when the file is approved, the properties of that file need to be updated. This step fails very often because the reviewer has the file opened, or just recently closed, making the file apperently locked.
So the flow fails on the 'update file properties' step saying (translated: The file <file URL> is locked for shared use by <name of the person who has/had the file open).
As a work-around on this, I applied a custom retry policy on this step, see:

As you can see, it should retry 90 times, every 30 minutes. But the total duration of the Flow that failed on this step is 5 minutes, so it doesn't respect the Retry Policy.
Any idea on how to get this working properly?
Thanks.
