Log into Jira and open Manage your apps from the Apps menu.
Click Stop Trial and the Unsubscribe from app popup will appear.
Click Unsubscribe.
Then, you’ll be able to click Uninstall. This will remove Time to SLA from your Jira Cloud.
The SLA configurations will be preserved even if you uninstall or disable the Time to SLA plugin. However, as a good measure, we recommend that you export your SLAs and calendars beforehand to avoid losing any data.
