Hi @Uwe_Moeller-Goebel ,
I understand why you'd expect an app implementation through Adobe Launch to behave the same way as it does for web but that is not possible as the Launch/Tags library for web runs inside the page’s JavaScript context. It can observe the DOM, attach listeners, and trigger rules on clicks, views, timers, data layer changes, etc. which helps in injecting behavior at runtime. However, in mobile apps there is no DOM to observe and no generic UI event bus the SDK can hook into and app stores also restrict downloading and executing new native code that would alter app behavior dynamically. Due to these restrictions the app implementations differ from web implementation done in Adobe Launch.
Adobe Launch in apps can listen to SDK events (Lifecycle, Places, Messaging, Push, etc.) and to app-dispatched events which can be used to attach/modify data on those events or trigger new events.
Cheers!
