Publishing Multiple Apps from one Unreal-Project

We are currently developing an application called “Example VR” for the Meta Quest 3 using Unreal Engine.
Everything works as expected — packaging, deployment, and testing on the Quest all run smoothly.

Now we want to release multiple versions of the app (e.g. “Example 1”, “Example 2”), so we tried the following:

• In Project Settings > Platforms > Android > Package Name, we changed it from
  “com.company.examplevr” to “com.company.example1”

Packaging still completed without any errors.
However, when we tested the build on the Quest, we noticed:

• The VR view was heavily distorted (one eye is missing or eyes misaligned, warped display)
• Textures were missing

Questions:

1. What is the correct way to publish multiple Android apps from the same Unreal project?
2. What settings could be causing these issues after just changing the Android package name?

Thanks for any help or suggestions!
