I see the same with conditional views where the non-default view has a searchable modifier with navigationBarDrawer placement and on first render the searchbar appears on the bottom, navigating to that view the second time has the searchbar at the right place. (on latest 26.4 beta as well)

To resolve the same error I had to wrap all Live Activity related code with #if !targetEnvironment(macCatalyst) ... #endif

Same issue on latest iOS 17 beta. Submitted FB12773661.

iOS (16/17) and macCatalyst, same behaviour in each case.

Is there any change to this with watchOS 8?
