I have a Samsung Galaxy 7 with Android 8.0 and a external sd-card 64GB. Since few weeks apps can't reach files on the sd-card anymore such like images and maps. Also my ES file explorer can't see them. But when I read with the app Samsung My Files or from PC, than there are all shown! I tried using a other new and new formatted card with the same result.
What could be the problem and how to fix it? Thanks for your idea and knowledge.
