Magical In-Game Bug Report

CS doesn’t handle nor forward bug reports: We submit bug reports through the In-Game Bug Report in the Europe Region.
Reports submitted in this fashion will not receive a response. Instead, they’ll be directed to the teams responsible for addressing them.

That said, I see more reports on the US bug reports forum about this so its a widespread matter. I recommend the above option to make the responsible people aware about it.
