It seems that experiencing delays in cloud-based flow executions in Prefect can occur due to a few reasons:
1.
Infrastructure and Worker Setup: If you're using Prefect Cloud, ensure that your workers are properly set up and running. Workers are responsible for checking scheduled flow runs and executing them. If there's any misconfiguration or if workers are not running, delays can occur.

2.
Concurrency and Priority Settings: The configuration of work pools, including concurrency limits and priority settings, can impact the order and timing of flow executions. If concurrency limits are reached, flows may be queued, causing delays.

3.
Issues and Bugs: There are some known issues related to delays and flow execution that have been reported in the Prefect GitHub repository. For instance, infrastructure creation failures can lead to flow delays. Prefect is working on adding retries for such cases.

If your flows are consistently delayed, it might be worth checking the configuration of your workers and work pools, as well as reviewing any ongoing issues in the Prefect GitHub repository. If the problem persists, you may consider reaching out to the Prefect community or support for further assistance.
