Massive delay only in online matches – FC 26 PC

Same here too. Some have it better than other. Clearly shows when playing online against people with what feels like 0 ping.

Shame nobody will help us. They will always say it's you. 

I think it has to do something with the kind of degenerates you might be facing playing on high ping WiFi or even data. Compensation exists, and there is a syncing issue. It really shows with play styles triggering without input.
