Android return type is not working.

[Hongrang]

Hello, nice to meet you guys :)
I'm new here.
I was trying to apply UnityNativeEdit plugin to my project but I found that return key type is not working on PC and Android.

I tried to use Multi line new line and single line submit inputfield on Android and PC but when I press return key on PC and Android they just ignore the key event.

I have no idead how to fix it..

can you guys help me?

I'm using Unity version is 5.4.1f and Android 6.0.1

I found that multi line is working when I'm using existing Custom input type.
with some editing.
