Unity Multiplayer : Player childrens movement & rotation probelm

Hi every one… I’ve create a simple 2D multiplayer tanks game… So the Barrel o every local player works fine but the other players barrel doesn’t rotate… they are just shaking…
the barrel it’s a child of the player & I think there is a problem with the “Network transform child” cause i didn’t understand it very well…

I’ve recorded an short video, Hope it’s make it easier to understand :heart: : https://b.top4top.net/m_94975yee1.avi

and this is a photo of the Player components :

AnyOne ,??

I have the same problem with a player child (the player’s weapon).
It is not rotating up and down in the other player’s screens.
Did you solve this problem?
