Hi,
Error message complete:
App update required
Your app Check It for Jira (Issue Checklist) is no longer working as it uses a deprecated platform feature. Please check if an update for this app is available through Atlassian Administration, or ask the app developer to upgrade the app. If the app is listed on the marketplace, contact the developer using the Support tab.
There is not update and not support.
Any suggestion for recovering the list of the checklist before this update breaks everything?
Thank you
