How do I deal with Apple's App Store promotional PSD templates?

Hi folks,

Apple contacted us because they want promotional contents from our App.
To do so, they're providing (you obviously know it), AppName_AS_FeaturingAppsGames.psd, AppName_AS_FeaturingToday.psd, AppName_AS_ProductPageArt.psd, AppName_AS_SupportingImagery.psd, AppName_AS_TitleTreatment.psd

Those PSD files have generally a specific structure, containing "smart objects" etc.
My problem, is that I'm no longer using Photoshop. I'm done with Adobe, seriously, I don't want them to get my money, and even more, I don't want them to touch my computer anymore.
So my computer is totally clean from anything related since more than a year now and I won't switch back. I knew/used for to long their apps to be able to hate almost any single parts of them.

Question is: how do I satisfy Apple if I cannot open the exact structure of the file they are providing?
How did you managed to provide them with —your– promotional contents? Did you used Photoshop? That's embarrassing…

Would be nice if you could put pressure on Apple (you can, I cannot), so they offer more formats, ideally .affinity.
Else, please make your import of PSD files more efficient

Thanks for your time, I would love earring back from you.

Ok,

I've been able to find a friend's computer with Photoshop installed.
It appears that those Apple's files are not anymore containing Smart Objects (they were by the past), which solve my wonders.
I was also mislead by Apple's own texts on guidelines: They are talking about a "localisation" folder that in fact doesn't exist on their provided contents.
In the end then, I've compared all files and Affinity Photo is importing them perfectly.

Solve my fear.
Still, since Apple start providing other format on UI (like Sketch files), would be nice if you push them to provide Affinity format

All the best.
