Experiencing the same thing, have you managed to find a solution??
@ColdFire1Well I upgraded to 1gig broadband and still got the stuttering, rubber banding or whatever is is, I've even bought a separate router but it still does it, doesn't always do it every round but sometimes starts during a round. Still doing my head in. EA support have told me it's their issue and a know issue, I've got a cable repull early January and also another ISP installing, so going to check it on that, you don't need super size broadband for online gaming. I'm certain it's their end.
My son plays other games fine on PS4 pro and ps5 like Fortnite, black ops and others with no issues.
I'm still getting it on PS4 pro.
