How do I ignore or unignore a crash?
If you would like to ignore a crash so it no longer appears in your reports, find the error in question and open the Crash Details popover for it. Then click the Ignore this Crash button. When a crash is ignored, it will no longer be tracked and will be retroactively removed from past reports.
If you have ignored a crash and want to unignore it so it appears in your reports again, go to the Manage Crashes page and click the eye icon for the error you want to see again.
