Jira doesn't refresh JWT tokens for Connect app integration

Issue Summary

We and our customers have noticed that Jira Cloud has stopped creating new JWT tokens for Connect iFrames. When a user is interacting with a Jira board for more than 15 minutes and then opens an issue modal, the Connect apps receive an expired JWT token. All apps are, therefore, broken, and the page needs to be refreshed.

Steps to Reproduce

1. Install a Connect app that works in iFrame.
2. Do not interact with the Jira. Just use the app inside iFrame.
3. After 15 minutes JWT token expires.

Expected Results

JWT token should be refreshed when an end user is on the same page and interacts with the app.

Actual Results

Unauthorized error message.

Workaround

To generate a new JWT token, please refresh the page.
