Question regarding warnings encountered with Unity (non-CN) version 2020 and above #349

We've encountered the following warnings when running an android build on Unity 2020.3.36f1 with UIWidgets version 1.5.4_stable:

1. Shader warning in 'UIWidgets/canvas_convexFill_cb': use of potentially uninitialized variable (shader_gradient_colorize) at <project-folder>/Packages/UIWidgets-release_1.5.4_stable/Runtime/Resources/shaders/UIWidgets_canvas.cginc(72) (on d3d11)

   • Aside from UIWidgets/canvas_convexFill_cb, we are also encountering this warning in the following shaders:
     • UIWidgets/canvas_strokeAlpha_cb
     • UIWidgets/canvas_tex_cb
     • UIWidgets/canvas_convexFill
     • UIWidgets/canvas_tex
     • UIWidgets/canvas_stroke0_cb
     • UIWidgets/canvas_stroke0
     • UIWidgets/canvas_strokeAlpha
     • UIWidgets/canvas_fill1
     • UIWidgets/canvas_fill1_cb

2. UnobservedTaskException:System.NullReferenceException: Object reference not set to an instance of an object

External Tools:

• JDK: Installed with Unity
• Android SDK: 30.0.3
• NDK: Installed with Unity
• Gradle: 6.5.1

We'd just like to confirm if these warnings are related to the fact that there is currently no official support for Unity (non-CN) version 2020 and above.
