App user missing product access

Issue Summary

• Sometimes, the original confluence-users group would be deleted or the default group altered by the customers. When this happens, the add-ons would lose product access on Confluence, failing to work properly (at least, most of them).

Steps to Reproduce

Attempt to use or configure any apps.

Expected Results

The page/app should work as expected.

Actual Results

Error message shows up in the UI or network logs:

• Something went wrong! Please try again later
• Unauthorized
• CONFLUENCE_FORBIDDEN
• Current user not permitted to use Confluence

Workaround

The solution for this scenario consists of granting the atlassian-addons (default system group that apps automatically belong to) product access on Confluence. Please contact Atlassian Support team to have this performed.
