Problem with gallery app:
I took a photo in graphene camera, clicked the photo in the bottom right, hit the edit pencil on top, cropped the photo and pressed save. It tells me Could not read the image due to the editor not providing read access.
So I went to the camera app info page, went to storage, configured storage scopes to allow access to DCIM PICTURES and EditedOnlinePhotos directories.
Then it gave me some unknown error message.
But the thing is, before I even configured storage scopes, even though it was giving a permission denied error, it did save the edited photos to the EditedOnlinePhotos directory.
