In 5.1.1, the depth calculation is not functioning properly on mobile ES 3.1 preview, resulting in reflections occurring in areas where they should not.
When checking with RenderDoc in ES 3.1 Preview, it was found that DepthAux was not being rendered correctly.
In IOS Preview, SceneDepthZ buffer is being used instead of DepthAux and working properly.
unzip and open attached sample project using UE 5.1.1
change to Mobile ES 3.1 preview mode
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-177957 in the post.
