So I have seen various topics that are similar, but can't find my exact problem. I have a Stylo 3. I have had it a little over a month. I have had a few apps on my sd card the whole time. But the other day, I restarted my phone, & 5 apps that were on my card had uninstalled. So I reinstalled 3 of them. When I moved them to my card, they stopped working - won't open, & keep getting pop-ups saying they aren't working, even when I'm not trying to open them. There were a couple of other apps that had moved back to the pbone, & after moving them back to the card, they work fine, except that one won't let me download new books on it. Anyway, other apps on my card work fine. Pictures & music are okay, too. So I'm not sure if it's the card, the phone...Idk....any ideas/suggestions?
