Hi James, I have the same problem, but reposted the question because I was going in the other direction, trying to make it NOT work on Macs and focus solely on getting it to work on iOS. So if I get an answer first, I'll post it back over here as well. https://developer.apple.com/forums/thread/666673

Thanks shelleygeek! Just to be clear and to make sure I understand ... you're getting it to work on projects that you've started over, but not when you try to update existing projects? Thanks again!

A couple more days of digging around on StackOverflow and whatnot, and it appears to be something that just popped up after the Apple Silicon announcement, and is probably a problem on Apple's side. https://stackoverflow.com/questions/64838331/stickerpack-for-ios-messages-deployment-error-warning-itms-90863-apple-silic/64879167#64879167 This might be the type of thing you need to sort out with Apple directly. I'm working on my first sticker pack submission this weekend, but it will be an extension of an existing app. There is a reasonable chance that the Big Sur launch changed App Connection's type-of-submission handling, and standalone sticker packs was broken. – benc 2 days ago I'm assuming that "sort out with Apple" means to file a radar. Here's my attempt, but I had no idea how to attach any diagnostics that would help, so if something comes to mind, please take a stab at it: https://feedbackassistant.apple.com/feedback/8903574

I'm following this thread in half a dozen different places ... a radar, three developer forum threads, and three stackoverflow questions. All dead ends so far. To me, this implies it's a glitch with the latest multiple updates, because none of the institutional knowledge base are chiming in with work-arounds. Filing a radar is the only thing I can think of to do at this point.

I think you saw the reply in StackOverflow but in case you didn't: Go to your app on the Apple Connect Website Under Pricing and Availability you will find a checkbox "Apple Silicon Mac Availability - Make this app available" If you uncheck this it should stop giving you the apple silicon warnings.
