Unity Multiplayer Question - Loss of virtual joystick control when a player joins the server (PUN)

I'm trying to create a mobile phone multiplayer game which uses a virtual joystick control to move the player around (airplanes). Currently, when the first player creates and joins an empty game room, they are able to move around as intended. Once a second player connects, both players lose control of their characters. I've noticed that the positions of both players are still synced but not the direction they're facing.

Here is the movement script:

Code (CSharp):

1. using System;
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5. using Photon.Pun;

28.     //Joystick params
29.     float MovY, MovX = 1;
30.     Vector2 JoystickDir = Vector2.zero;
31.  
32.     //Wing behavior
33.     public float wingDrag = 1f; //this is for how much you slow down when you turn and how much of
34.     //this force gets converted into forward movement, like wingsize
35.     public float wingLift = 0.5f; //this for when you don't want your plane to crash (I'd rename it)
36.     //crashability but like that's ultimately unhelpful
37.  
38.     //Directional change vars
39.     bool rightFacing = true;
40.     float timeSinceDirChange = 0;

122.             rb.AddForce(horizontalVelocity * -Vector2.right * wingLift);
123.  
124.  
125.             //adding check to flip y scale of playerobject
126.             //
127.             if(rb.velocity.x < 0)
128.             {
129.                 if (rightFacing)
130.                 {
131.                     rightFacing = false;

137.                 {
138.                     rightFacing = true;
139.                     Flip();
140.                 }
141.             }
142.         }
143.     }

145.     private void Flip()
146.     {
147.         //TODO: trigger to activate animation
148.         transform.Rotate(180f, 0f, 0f);
149.     }
150.  
151.     void ChangeAnimationState(string newState)
152.     {
153.         //stop the same animation from interrupting itself
154.         if (currentState == newState) return;
155.  
156.         //play the animation
157.         afterburnerAnimator.Play(newState);
158.     }
159. }

Here is the player instantiation:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using Photon.Pun;
5.  
6. public class SpawnPlayers : MonoBehaviour
7. {
8.     public GameObject playerPrefab;
9.  
10.     public float minX;
11.     public float maxX;
12.     public float minY;
13.     public float maxY;
14.  
15.     private void Start()
16.     {
17.         Vector2 randomPosition = new Vector2(Random.Range(minX, maxX), Random.Range(minY, maxY));
18.         PhotonNetwork.Instantiate(playerPrefab.name, randomPosition, Quaternion.identity);
19.     }
20.  
21. }

Here is the hierarchy of the player prefab which might be the issue:




Any help/advice is much appreciated, thanks!
