I definitely agree that it’s really annoying how it’s been radio silence when there’s so many people asking about it.
As annoying as it is, I’m like 99% sure it’s Apple that is holding things up. Unfortunately that’s out of SDS’s control and it likely is due to Apple’s “App Review” process. I’m a developer and have encountered stuff getting hung up for a week randomly, pretty much for no reason at all. It’s usually like a 24-48 hr process, but it can take longer when aspects such as “account verification logins” are involved (such as logging in through XBOX, PlayStation, Switch).
It could have been easily mitigated by submitting it at least a week in advance. It’s not like they didn’t know it was coming. Given how many people pre-ordered with expectations of their app being functional on their Apple products, it’s a really big screw up on SDS’s side.
