I have a post function that sets a field in JIRA and it all works correctly. It shows in the activity log that the field is set, but if you look at the ticket view or edit screen it is still blank. Then after about 10-15 minutes it finally updates and shows the correct value. This causes a lot of issues because I want to fast track certain issues to be resolved based on this field, but can't. What is going on here and how can I fix it?
