PC Controller NOT WORKING online

Hello,

I'm experiencing a serious issue in EA Sports FC 26 on PC.

My Xbox controller works perfectly offline, but in Ultimate Team online matches, after a few minutes, my players become unresponsive or delayed. Movement becomes erratic, while menus still work normally.

I have already tested:

- USB connection (no Bluetooth)

- Disabled Steam Input

- No duplicate controllers

- Stable Ethernet connection

The issue only occurs in online gameplay.

This makes matches unplayable.

Please advise or confirm if this is a known issue.

Tell me please, will I have same problem if I used PS5 controller instead of my Xbox one???

Thank you.
