Ping doesn't always work

I have set my ping keybind to “G” - and often it works just fine, but randomly it will just stop working either in a new match, or sometimes halfway through a match. Just, forgets it is bound to “G”. I check in my settings mid game, all looks fine, bound correctly, nothing out of the ordinary. It just-- simply doesn’t work…

It greatly messes up gameplay flow when I’m in a hot duel trying to ping someone and suddenly it just doesn’t ping anymore. The strange thing is that most of the time it works flawlessly, so I really can not tell what the issue is, and I have not been able to find any noticeable pattern for when it stops working. I never tweak my settings, I never do anything out of the ordinary. It just, stops. No idea why. And I’ve heard similar reports from a lot of other players - and with communication being so integral to the game, I really hope the devs are on top of this issue and trying to find a fix.
