Lyric Pad does not recognise folders in SD Card

In clear words: using an Acer Iconia 10 with a 32GB SD card I can't use this external memory?! To avoid internal memory overflow I need this external extension! (I have more apps than just lyricpad)

I know this is old, but was this issue ever resolved? I'm having exact problem with LP2

LP still doesn't recognize an SD card. It's blamed on Android memory permissions. The card is there in other apps and files management view. I copied lyric and audio folders to the SD card and set the folder location to the SD card in LP and LP still defaults back to internal memory. I gave up.

Long story, but thing is, it was using the sd card for years on both my tablets. bought a new tablet couple or three years ago and left LP on the old one. for a back. Fast forward to few nights ago. Wife was using the old tablet and had recently deleted LP to make room on internal memory. Well, we needed both tabs for a gig. All the Lyric files were still on the old tab, on the sd card. When re-installed LP, the sd card did not come up as an option.
So... i looked at mine and sure enough it showed the sd card as the location. Then... I selected the sd card on mine, and it just disappeared. poof. Couldn't get it back. As per instructions on one of these questions, i reset LP. Nothing. Nada. Just did some emulated directory somewhere on the internal drive. Absolutely no option to select sd. It worked years like that and now... nada. And yes, the permissions are there as are the files.
