Why can't I select some image files on some apps, while the Gallery app can? I have a Xiaomi device on Android 8.0 Oreo. I was editing some pictures in an application and sometimes the picture that I want to edit doesn't appear on the editing app, but there's in the gallery.
Why and how to fix this?
Photo app can find photos stored on device memory. It support some file extension like png, jpg. If file extension is not supported then it will not appear in photo apps.
You can update apps and also reset it.
