External SD card and Lollipopquestion

I have a Moto G 2014 with Lollipop 5.02 and AirDroid web fully recognize the external SD card.
Already in the LG G Pad V480 with the same version of Android and the same external SD card,
the Airdroid are not allowed to write to the card... Why?

You can manage files on external SD card on Moto G running Android 5.0.2? Is it a external SD card?

Generally, manage files in external SD card on Android 4.4+ is not supported by current AirDroid because Google has restricted the access to it. Sorry about that.
