I’m having trouble using these instructions to obtain a sysdiagnose file from the watch. Holding the crown and side button for 2 seconds doesn't appear to work in watchOS 4.3.2 or on this older watch model.
I see your note that apps that worked on watchOS 4 previously should launch just fine when compiled with the latest SDK. I should note that I am using the same exact source code as what's in the App Store right now. The only difference is the store version was built with Xcode 15 and the one that errors was built with Xcode 16. I can download the version I have in the App Store right now and it launches and functions as expected on watchOS 4.
