I have a Moto X Pure Edition with Android 6.0. I installed a Samsung Pro 128 gig SDXC U1 card and formated it as internal memory. I was expecting to store a lot of music on the card, and I like to play games that take a lot of space. Whenever I need to reboot my phone, most of the apps I have installed on the SD card vanish. They are gone from the Home page, gone from the App drawer, all files gone from the SD card. If I reinstall the app, all the user information is preserved, although I could not find any files on the SD card. A salesperson at the AT&T store thought that the SD card is taking too long to mount, and the launcher is skipping it. We tried to install Nova Launcher, but it behaved the same. I specifically bought this phone because I could expand with the SD card. How do I fix this?
