Two accounts, two different gameplay experiences

I have two ultimate team accounts on the same ps5 console with the same internet connection and everything else is exactly the same. However online gameplay on the secondary account is far better than the main one. The mechanics, speed, and responsiveness are executed exactly as is expected. On the main account the squad is slower, if I tackle or intercept, the ball bounces straight back to the opponent. Manual defending is non existent, and offensively the attackers rarely can break the defense. Even though my main account has meta cards they feel like common golds. On the other hand the second account has mid tier cards and yet they play far better than the other. As I said before. I'm playing on the same console and internet, the same tv. Basically everything is the exact same except for the account. Can someone look into this and help me fix my main account so that it actually performs as it's supposed to? Because surly both accounts should perform identically. Why is there such a huge difference between these two accounts?
