2D Rotation not syncing over the network

I am currently making a 2D PVP fighting game, similar to Tekken and Street Fighter games, but I am currently having a problem, syncing the rotation of the characters.

In the prefabs of the characters, I have attached Network Transform component, and i have selected it to only send the data of the rotation on the y-axis, but it still doesn't work.

Any advice on how I could sync the rotation of each characters?

Thanks for any help in advance!
