Second player's screen does not render in Split Screen on Android

The second player's screen in a Split Screen multiplayer session on Android does not render. It remains completely black. This was also an issue prior to 4.15 but was fixed with [Link Removed]. The fix applied still seems to be present in the current files but the issue has reappeared.

As this is a mobile issue, I also tested this on iOS and it does not occur.

Regression?: Yes
This does not occur in 4.20.3

1. Create a new project based off the Third Person template.
2. In the Level Blueprint, add a "Create Player" node that fires on "Begin Play".
3. Package the project for Android.
4. Install to an Android device and launch it.
   Result: The bottom screen does not render.
   Expected: The bottom screen renders properly.
