Hi,
i am experiencing the issue in subject whatever the editing app i use (so i guess it is something at the operating system level). For, instance, if use Focos to add a bokeh effect and save the edited picture, when i open it in Affinity Photo the bokeh is being removed. Same thing with cropping made in the Apple Photo app, so when the cropped image is imported in Affinity Photo it’s being restored to its original un-cropped version.
