If Jira license changed to higher, Does Tableau Connector for Jira require the upgrade as well

According to Atlassian Licensing rules, the app user tier must match the parent product user tier. Cloud marketplace applications naturally match the tier of the host product within the cloud site and are unable to exceed the host product tier. Therefore, if the number of users in your Jira instance increases, you will be charged more for additional users for the application as your current licence will be upgraded to the number of users in Jira.

Cloud subscriptions paid monthly will simply charge the card on file for the number of users tied to each product, each month.Cloud sites paid annually will need a formal prorated upgrade quote, as products are sold in distinct user tiers. Please review the available annual user tiers and Contact Us for a formal upgrade quote.
