Massive bug with pings! PLS FIX!!

I just had 2 teammates with major ping bugs!!! Jûstin & Ipp Entire game they had major issues with ping system. It would not appear or notify them when someone else on team was pinging. It didn't matter what type of ping or how many times it was pinged they simply could not see the pings happening. They would be happy to let you know exactly what was happening if you message them but it made for incredibly difficult game play that resulted in a loss.
