What’s happening?
Approval flows in Power Automate are timing out after 28 days of waiting for a response, leading to failures in the flow execution.


Reason:
The timeout for approval flows is enforced at 29.5 days, and any flow still running after 30 days will fail. This is due to the run duration limit for Power Automate flows, which makes it difficult to trace errors if a flow times out, as the retention period for flow run history is around 30 days.


Resolution:
To mitigate this of approval flows timing out after 28 days, consider the following steps: 

  1. Avoid long-running flows that approach the 30-day limit.
  2. Break down the approval process into smaller, more manageable steps that complete within the time limit.
  3. Regularly monitor and manage flow runs to ensure they do not exceed the duration limit.
  4. Use logging and error handling to capture and address any issues promptly.
