[2020] Extreme constant all day rubberbanding

Hello @Pehrr, welcome to the community!

Which server did this occur on, and what is your friend’s internet speed and ISP?

Can your friend test a few different servers, and is he able to ensure his console is on a wired connection?

Has he tried running a multiplayer connection test?

Thank you for clarifying, the rubberbanding on login/teleport will be addressed in today’s hotfix.
