I have approval escalation timeout set in "Start and wait for approval" and also configure run after timeout for escalation step. First time run was successful as expected to escalate to 2nd level approval. However, was unable to escalate for subsequent runs.
Whenever I edit the flows and check the timeout value set but was blank.
In order to get it working again, I had to re-key in the timeout value again every time.
Timeout set, escalation approval OK
Set timeout value. But value disappear when edit again
