Good to know:
✔ If the sd card is formatted as adoptable storage, the app may unable to access it directly. In that case either move the app to the adoptable storage (change the install storage), or format the storage as portable storage.

Common reasons: fake sd card, slow sd card reader/hardware problems of the phone, software problems.
Easy to use even for beginners. Quick tests.
