My hope is that they’re coming up with a more comprehensive solution than might be guessed.
For example, although I greatly desire the New Batch Job to function properly with other cloud storage besides iCloud, even if they fixed it there would still be a basic problem. When adjusting raw photos in Affinity Photo, there is no means to store or save your adjustment settings. Affinity Photo does not currently make use of XMP sidecar files, nor does it have any sort of library/catalog of adjustments you make to your files. This renders the New Batch Job function slightly less capable, even if cloud storage was functioning properly.
So in the BIGGER PICTURE of things, what I wish is that the developers work on both sides of this problem. Maybe that’s where they’re headed. No pressure, Affinity Developers.
