fc 25 companion

I am a fc25 ultimate team player My username is aliosman190719. In the most important parts of the game, while I am winning matches, there are constant disconnections, although my internet is not a problem. In a poblem, I get a package in fc 25 companion, I cannot select a player, the server gives an error. It's really sad! I'm investing money in this game and I can't enjoy it.
