Changes made by JMWE post-functions are not always visible just after the post-function execution. This is because JMWE post-functions (as any other post-functions implemented by JIRA Cloud add-ons) are processed asynchronously, after the transition completes. This helps ensure the stability and performance of your JIRA instance.

This problem is tracked by Atlassian at: https://ecosystem.atlassian.net/browse/ACJIRA-1098
