Can't delete some comments?

When trying to delete a comment, it's possible you're seeing the following error:

"Users can only delete their own comments published by the same app".

This means that CommentGuard can't delete your comment because Facebook returns this error when trying to delete it.

It occurs for a small percentage of the total comments we process every day. 

Sadly there isn't anything we can do to resolve this issue, because it's caused by a bug in Facebook's API. We found that this is a known issue that is acknowledged by Meta and which is reported often in Meta's developer forum. We're tracking the main bug report for updates.
