My game keeps desyncing on ultimate team

Hi there. What platform are you playing on? We'll go through some troubleshooting.

Ps5 but I switched to my cousins account and played on his account and had no issues. I switched back to mine and it started desyncing again

Are you playing on the same console? If not, are you using shareplay?

I put his account on my console just to try it and I’m not share playing with anyone 

Try rebuilding the database and clearing the system cache with the instructions here. Also, restore your licenses with these instructions.

We’re on the same console but I did a one time user thing to see if it’d work and it did but my  account desynced

Take a look at your network settings on your PS5. Let me know what it says for the NAT type.

Type 2

But why would my cousin account work but not mine and it’s on the same system 

Are you playing on a wired or wireless connection?
