Just re-confirmed this bug as present on an iPhone 6s using iOS 14 Public Beta 2, with the app downloaded from the App Store. Before update - launch storyboard was fine. After iOS 14 is installed, storyboard is black. No help / advice yet from Apple.

It seems that there was some kind of update or change to the way that the SDK renders PNG files. So I had to re-export everything as JPEG and everything worked. I couldn’t find anything in the release notes that mentioned the changes to the JPEG and PNG handling or rendering but this was the issue.

Yes it will be rejected, as you already know from reading the rule.

If you actually bother to read it, it's clear. If you make any money from the app, either one-off purchase, in-app payments or a subscription, you ARE A TRADER. Whether you are trading as a company or like many, a hobbyist or individual. This means under the draconian DMA, your personal name, home address and personal / home phone number will be visible on the App's storefront for the world to see. No where else online does it force you to share your private information like this; it's dangerous, it's an invite to doxxing or personal attacks. You don't need to do this for social media accounts, for music accounts, for linked in or even dating sites. But if you sell an app on the fractured App Store in the EU or to any of the 27 member states, you have to show this. It's ******* disgusting. The people who did this should be ashamed of themselves.
