Setting use controller pitch across server and client? [with video]

Hello everyone, I’ve set up a system in which the player switches to use first person arms when aiming, however in order to get the arms to move up and down, use controller pitch needs to be enabled. The issue is that while in multiplayer, the player’s pitch is replicated no matter what, so when I look down in multiplayer the model looks downwards as well. Here’s a quick video of the issue: ue4 use pitch issue - YouTube

You can see it works fine for the client, but not for the server. Thanks for any help in advance!
