Hi
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.

Is Vuforia included in the first Unity scene? The “StreamingAssets” folder where the Vuforia datasets are stored is one of the locations which Unity will store in the OBB if the APK exceeds 100MB. The existence of the necessary datasets in “StreamingAssets” should be confirmed prior to starting Vuforia. It is recommended to not have Vuforia/ARCamera included in the first scene if the APK is split. See these additional links for more details:
