Thought I would close out this tread with this response that I just received from ASUS tech support:
"Since Android 5(Lollipop) Google removed/disabled the feature to allow applications to be stored on an external source(SD card). However you may see some devices with the feature as some manufactures have designed their own firmware to unlock the feature. Our devices do not have the feature which means you are only able to store files such as; Music,Pictures,Video etc on your SD card."
Appears that I was blaming the wrong people.
