FC26 Horrible Connection

Every time I play rivals or FUT champs i lag. I check my internet and its at 850+MBPS and when I load into the game is says usually between 15-20m/s, but when i begin the game and start dominating and/or winning my m/s shoots to 400-999m/s. I checked the EA connection quality report and i’m at a score of 95/100 with everything looking perfect and still lag. I checked everything and changed settings and nothing works. I also play other game modes or other games and i don’t lag. I literally only lag and get horrible connection when I play Rivals or FUT Champs. I truly believe this is because of EA’s scripting/DDA code. It literally happens in rivals/fut champs and when i’m dominating a game or when i'm winning. I really hate this company and wouldn’t be surprised if they added it to their code since I’m not an EA donor and don’t spend money on this awful company.
