Any updates? We’re having the same issue.

I also have the exact same issue. Since I could not find your forum beforehand, I created a thread as well: https://developer.apple.com/forums/thread/809806 The zoom navigation transition does not work in tabViewBottomAccessory if you interact with a @Published property from an ObservableObject. However, the zoom navigation transition in tabViewBottomAccessory works with @State. I hope this gets fixed soon, since we need ObservableObject.
