I'm using Moto G5 Plus (32GB) with the latest updates (Android version: 7.0 Security patch: April 2018). Somedays back I noticed something wrong with my SD card. It's not showing in file manager app(Motorola's default) but I could see it in settings>storage. I have installed ES File Explorer and I can see SD card in this app and access contents of it but I'm unable to delete or copy (its like having only viewing rights). I have also tried connecting it to PC and it just showing only Internal storage.
