If I Export the Picture from the App into the iCloud, the Pictures has the current Date stamp and not the real Date stamp on which Date the Picture is realy made before? In that case the Pictures aren't in correct Date Sequenz in the iCloud to maybe other Pictures from the same Journey? Do you understand my iCloud Problem ? The Pictures aren't listed in the correct Date Sequence anymore.... and ideas?
If you export the image, creating a new image, it is a new file and it receives the date/time stamp of the operating system. That's how creating new files works. I don't know of any way to circumvent that.
