From the last Unity 5.4 version, there is a problem to publishing Androids apps with a size > 100, when you need to split and generate OBB files: the scene with AR takes 5 minutes to load, when before Unity 5.4 the same scene take just 15 seconds. Any other scene without Vuforia AR load as fast as always. Looking in forums in UNITY i have found several users with the same problem.
Thanks in advance.
