[ I am using Google Chrome (Windows 10) ]
As stated in the Topic title, I have experienced a rapidly flickering error page that opens when you search for a Gamertag on my service record page for MCC.
I am not susceptible to any harmful effects from it, but it is very noticeable and uncomfortable.
So please be wary until you know it’s fixed.
If you are experiencing the same or similar effect, please state your platform/browser/etc.
Of course, don’t do this if you believe it is harmful!!!
