[2020] Enemy lag online servers. Offline works fine

Hello @ShadoWolfspirit, welcome to the community!

Does your wife play on the same console or a different one?
Does she also play on the same server?

Is your console on a wired connection and do you have any issues with other servers?

Could you specify the server numbers for those who give you connectivity issues?

Which PS4 models are you both using?

Have you tried to perform a clean reinstall of the game or to rebuild the PS4 database?
