[2021] Literally can't play

So I have a switch lite and I got rocket league bc I wanted to try it as I've never played it before. I've done the tutorials and sh*t and I try and play casual but it straight up will not let me. I can't play at all for some reason. Like I can do freelance and training and all that. But that's it. I can't play casual whatsoever. I'll like hover over casual click a to choose it and nothing ever happens. Anyone know why or what I can do :/
