One of the app's features is the search of potential duplicate filters. As the search can be slow and heavy due to the number of filters in the system, this search to be performed not in real-time but on a timer as a service.
The default timer settings are: once a day at 1 a.m. (server time). We recommend using the service during the minimal Jira using time (i. e. at night) since the service might be heavy in case you have too many filters in Jira.
These settings can be changed in the Administration → System → Services section. Check and change the settings if required. You can also navigate to the service from the admin section of the app.
