Character 3d partially renders on Android after upgrade on 2018.3 from 2017.2

After upgrading to 2018.3 (I tried 3 to 9), my character 3d are renderer partially.

The characters are imported from Mixamo (Remy and Maws).
They are not animated, just a basic scene with characters in T-pose.

It works on Ios and 2017.2

I know it is not a question of materials. I trtied with a yellow standard shader and got the same problem.

@TheNenet I have been having the same issue - did you manage to get it resolved?
