Pantech Element Storage Problem

[AC Question]

I have two problems.
1. When I put in a microSD card (8 gb) nothing happens.
2. My tablet says I have over 11 gb of free space, but when I try installing apps (which definitely don't take 11 gb) it says "insufficient space"

Welcome to the forums. Is the card on the proper format? As for the storage space, is there any way you can provide a screenshot of the storage stats, please?
