I am hoping someone from the review team could speak to this.
I just received the email saying starting in April all newly submitted iPhone apps must support iPhone X super retina display. My first question: is this also for updates to existing apps submitted in/after April 2018, or just new apps? Previous emails regarding changes to submission requirements usually specified "new and update submissions" but this one doesn't. My second question: will pillar boxing be considered acceptable for iPhone X support? While this most relates to existing apps (so sort of a null point if the first question's answer is "just new"), for full screen games, reworking content to be visible on the ultra wide (for landscape) screen is a notable amount of work, whereas adding black bars on the sides can be significantly easier.
I realize that this would meet the letter of the requirement, but not the intent. Would this be treated as an acceptable but not favorable solution, or as a rejectable offense?
