After you connected the first time to your Jira site or your license expired, you will see a message to license the app.
To license the product the SharePoint site collection administrator must add an entitlement number for the product under the selected Jira site. This number is used to verify the license status of the product. Users without sufficient permissions are only capable to see the license status. The entitlement number for the product can be found in your Jira site under Manage Apps.
Adding the entitlement number
Edit the entitlement number field by clicking on edit
Enter the entitlement number for the Jira Site
Click on save
If no error occurred, you will see the entitlement number in the field and the current license status
By clicking on the cross icon, you will cancel the saving
The license is bound to your Jira site, where you installed the SharePoint Connector for Jira. This means your are able to use the product in every SharePoint tenant you want but can only connect the one Jira site. If you want to use also other sites, you will have to buy a separate license.
Be aware that it could take some hours to update the license status for new purchased products. You are still able to add the license in the WebPart and we will revalidate your license status automatically from time to time.
After the validation succeeded you are able to use the app. This configuration has to be done only once per Jira site. If other users add a new WebPart, they could use directly the licensed Jira sites and start to link Jira issues.
