Data is not saved when connected EA account to Nintendo Switch

Hello,

I recently bought EA FC 25 on Nintendo Switch and linked it to my EA account for Ea Fc 25.

I  logged in and when I went on Ultimate Team all my data is gone.  I was really mad about that since i had already put alot of effort in on my Playstation ( I had bought Ultimate Edition on playstation).

Any ideas why this is happening.

Thanks
