How to reproduce:
1. Open the “ReproProject“ project
2. Open the “Scenes/SampleScene“
3. Build and Run for Android
3. Observe the right-most white rectangle

Expected result: The second render texture is rendering the “Camera (1)” view immediately after creation
Actual result: The second render texture is rendering black immediately after creation

Reproducible with: 2021.3.46f1 (URP 12.1.15)

Not reproducible environment: No other environment tested

Workaround:
1. Have the package somewhere on your drive. For example: install “2021.3.15” and add Universal RP (12.1.8).
2. Go to your “2021.3.44” project and open the Package Manager window.
3. Click '+{*}'{*} and choose the “Add package from disk….” option
4. Find the “package.json” file in the “12.1.8” package folder.
5. Add that package to your project.

Notes:
- Not reproducible in the Editor and Standalone builds
- Reproduces with both Vulkan and OpenGLES3 Graphics API’s
- Changing Depth buffer value or depth texture modes in the renderer does not change reproduction
- Seems that the last created render texture won't render the assigned Camera view, but will instead render black
- Seems to only affect the “12.1.15“ version of the Universal RP (com.unity.render-pipelines.universal) package, more information in the comments
