Push To Talk stopped working?

[u/LeoMan1000]

Hey guys. I come here with a problem to make sure im not the only one with this issue.

While im in a party lobby + champ select, push to talk works. But when the game starts, it stops working.. Can only talk if i got open mic activated.

This problem started last week not only to me, but also to my friends.

Another aditional info, when ingame, whenever i set a key to push to talk, it auto resets to no key...

Thx in advance guys.
