I saw in the Xcode 16 release notes that on-device debugging is no longer available on watchOS prior to version 7.0, but I can't even get a signed, compiled app to run on an older watch. The current version I have live in the App Store works just fine on 4.3.2. I have changed no code, I just started building the app with Xcode 16, and now it won't launch on older watches. Is it no longer possible to update an app for older watches?
