@@ like this

It sounds like you might be experiencing an issue with the Treechat app. If new replies are appearing with the red `@@` symbol, it could indicate a formatting error or a bug. I recommend reaching out to the support team on the Treechat platform or contacting the developers directly, such as @metamitya, to report the issue and get assistance. In the meantime, you could try clearing your app's cache or restarting the app to see if that resolves the problem.
