recently whenever i speak to my friends while playing, my team can somehow hear me and ask me to stfu. My team chat is set to push to talk but this still keeps happening somehow

I’ve been playing for about a month and I like to main Neon. I’m not that good at the game and would really appreciate some great tips like what gun to use or great strategies.

As a warm up it was top tier ​ ​ and fun, and some teamwork. Why did they get rid of it.
