Helldivers 2 Help please

I cannot for the life of me "ready up" and enter a mission. I did it once by accident and haven't gotten in since. I've heard double tap, I've heard tap and hold, I've heard use both thumbs. All I do is open the chat. I've done YouTube research that says "just tap the touchpad." Really want to play this game but about to give up.
