I have a problem With PTT

Good day my friends on TS … I have a problem… when I set Push-To-Talk to a button, I can’t talk can someone help me ??

which button you set it? send me a picture of it .
maybe we can see what’s wrong.

Are you using multiple hotkey profiles by any chance?
If you do, check if you are using the correct hotkey profile on the server you are attempting to use Push-To-Talk.
