I got tonight the info that it should work. I did a build and was able to distribute the app to the store :-)

I got an answer from Apple Technical Support: "Currently, the App Store Connect validation associates the background mode only with APIs that reference full-depth data, not shallow data. Since use of full-depth data requires an entitlement you don’t have, the validation currently rejects your App Store submissions." Currently the background mode with the shallow water entitlement will be rejected by the App Store. It's currently under discussion if they will continue with this or if they will change it.

Hi, I used the App Image Size (free in App Store with advertising) to resize 2 or 3 images. I put the photos in the store and the photos were accepted. The App cut some parts of the photo but it works.

this a screen shot of what happened
