SanDisk Memory zone does not see the external 32GB SD card on my Android tablet

Applications SanDisk® Memory Zone
6

I have an LG Stylo 2 android phone and I inserted an off-brand 32 GB microsd card. The phone recognized it just fine but the memory zone app wouldn’t. I figured it was because it was a cheap off-brand so I ordered and inserted a sandisk 32GB microsdhc card and the phone reads it fine but the app still won’t. Please let me know if anyone figures this out
