Adding the Compliance for Confluence App to impacted services.

In this App, if a Confluence Page does not already have a Classification Level, the level will not be possible to set due to the same issue impacting our other Confluence Apps.

We are continuing to investigate this issue.

If you have trouble loading certain pages or performing particular actions in either App, please check if you have the following symptom of the problem by opening your browser developer tools (F12) and note if the following error is being written to the browser logs:

Uncaught DOMException: Failed to execute 'postMessage' on 'Window': Symbol() could not be cloned.

We are investigating an issue effecting the Workflows and Approvals for Confluence Apps.

The Apps are failing when they try to communicate with the Atlassian Confluence API using the provided resources, which causes an unhandled exception which prevents the App from working - the easiest way to reproduce the problem is when trying to open the Page Byline panels of either App which appear on the top of each Confluence page where the App has been enabled.

A ticket has been raised with Atlassian to expedite a fix for this issue.

We are looking to prevent the issue from causing the App to fail by implementing additional request validation.
