Hi Peko
A 15-minute delay in pipeline triggers after merging changes could be due to several reasons. This could be due to temporary issues on Microsoft's side, such as queue congestion or service slowdowns.
Check Azure DevOps Status to see if there are any ongoing incidents affecting pipeline execution.
Ensure there's no new delay configured in your pipeline triggers.
If you're using a Microsoft-hosted agent, your job might be waiting in the queue due to high demand. If the delay is in "Waiting for an agent", it's likely a resource issue on Microsoft’s side.
Hope this helps!
Please Let me know if you have any queries.
