I have 2 apps on the App Store since 2009, and today I can no longer generate a Promo Code. I haven't generated a code for several months so the current app version still has 100 remaining. Any ideas, is it down?

I recently authorized my 10 year old app for use on Silicon Macs, to mimic an iPad. Vendors are reporting that my app downloaded via an iOS promo code does not allow them to also download my app from the MAC App Store. Even though they have the iOS app on their iPhone and iPad, the MAC App Store is asking them to pay. How can I create a promo code for the MAC App Store? My app is a Universal iOS app, and I only want it to work with Silicon Macs. I need to allow reviewers to download my app for free, as it's expensive, $29.99. Thank you.

I currently have an app on the App Store which has functions that work in portrait and other functions that work only in landscape mode. It autorotates much like camera does. I built it to test on Xcode 12 beta 3 on my Mac, but cannot see a way to rotate it to test in landscape mode. There are no visible buttons, and Ctrl-arrow does not rotate it like it does in Simulator. Any ideas?
