That’s fine, same as mine.
Are you playing in the evening your time, or at other times of the day (which may be less busy with people being at work/school)?
Unless you’re playing at strange times, it seems odd that you are having long matchmaking wait time’s unless there’s very few in the US playing this (which I find hard to believe).
Might be worth rebooting your router (and playing with a wired not wireless PS4 if you’re not already) just to see if that changes anything.
