Playing Ultimate Team is a nightmare because of lagging and latency

Hello,

I bought Fc 26 and live in Montreal, Canada. I have an internet connection of 500Mbps download and 50Mbps upload. When i test the latency with speedtest, it is around 10 ms. I play on luna premium cloud gaming, all the games are fine but not fc 26.

Playing online games in ultimate team is a nightmare. Sometimes it is good but must of the time, i can't play. What is strange is that, before the game, the latency showed in Fc 26 Rivals is between 4 and 20 ms but the experience is bad.  And sometimes the latency is 25 ms and the game is fine.

What is going on with EA FC 26 platform ? I deserve to play all my games with no problem.
