I have a Mac app in App Store Connect (currently in TestFlight beta testing). When I first uploaded the sample screenshots and clicked on them immediately after uploading, the images were clear.
Now, when I click on the preview images to see larger versions of them, they are much smaller and fuzzier than before.
Is this an artifact of the portal (perhaps just showing me upscales of the thumbnails), and when I release to the App Store the screenshot images will be clear again?
Or have I done something wrong?
