Who can I reinstall your app?
If you installed our app a while ago and didn’t purchase it before the trial ends, Atlassian will automatically uninstall it. Our Atlassian Marketplace apps without a paid subscription on a linked production environment can be added on a free trial with the option to add payment details at the end of the trial period. This means you can install apps from the Atlassian Marketplace or through the Manage apps screen from within the Jira Service Management administration section of your site and try them out.
Atlassian will send you email notifications to your billing contact email address when your trial period ends. Once the trial ends, you’ll need to add your payment details to purchase a subscription to keep using the app on your site. Otherwise, Atlassian will remove the application.
You won’t see an install or buy button in that case anymore. Please contact the Atlassian License team and request help with the installation since Atlassian Marketplace manages the deployment process.
