This has been partially resolved. As it turns out CFBundleDisplayName went missing from the Info.plist. Adding CFBundleDisplayName back resolved the problem with SiriTipUIView. However now ShortcutsUIButton suffers from the same problem. Often displaying just "shortcuts" instead of "APP NAME shortcuts" But the problem with ShortcutsUIButton is less of an issue because it doesn't look weird when it is just "shortcuts"

Thanks, that is exactly what I needed. Quick follow-up question, the article mentions a "default guide app". What determines if the app is the "default guide app", can the user set this in the interface?
