Why are my play music apps not reading my SD card on an Asus Zen Pad 10?

[Nirvana64]

I have both an Asus Zen Pad 10 and a Samsung S5. Both run Android 6. When a 128 GB micro SD card is placed in the Samsung, the Samsung Music app reads all of the files on the SD card and is ready to play them. The same app on the Asus with the same SD card will only find about 50% of the files. I have tried a number of other music apps on the Asus and get the same result as found with the Samsung Music app. What am I missing here and thanks in advance for your help.

Welcome to Android Central! What's the exact model number of the tablet? Are you sure it supports SD cards that large?

The Z300C specs say it supports cards up to 64 GB: https://www.asus.com/Tablets/ASUS_ZenPad_10_Z300C/specifications/. Larger cards might work, but they just can't guarantee that they'll always work correctly.
