  1. Resolution Note:

    Thank you for reporting a bug to Unity.

    After reviewing the behavior, we have determined that this is an expected behavior connected to low-end device support. Some of the slices of the Shadow Atlas are removed as a safeguard to prevent shadow slices from being allocated too small a resolution. This is further confirmed by a warning message found in the logcat: “Too many additional punctual lights shadows to look good, URP removed 2 shadow maps to make the others fit in the shadow atlas. To avoid this, increase shadow atlas size, remove some shadowed lights, replace soft shadows by hard shadows ; or replace point lights by spot lights”. You can either follow the warning message solution to avoid this behavior, or when using OpenGLES3 as a Graphics API, you can toggle “Require ES3.1” in the “Project Settings > Player > Android > Other Settings” under the Rendering section.

    We will close this case as 'As Designed.' If you have feedback on how the feature could better meet your needs, please let us know - we value your input and consider it in future improvements.
