use Firestore model value as toggle to present fullscreen view in SwiftUI

Question

I have two screens in a SwiftUI app. Screen A is displayed after the app launch and contains a button which will update the value for currentWorkoutID on the user model and save that modification to a Firestore database.

Screen B is shown from screen A when currentWorkoutID is not nil on the user model.

The problem that I'm seeing is that when I press the button in screen A, screen B immediately shows up (no animation), then is dismissed with animation and then is shown again with no animation.

I'm unsure what the issue is or how to solve it.

struct TrainingProgramDetails: View{
    @EnvironmentObject var workoutCompletionStore: WorkoutCompletionDataStore
    var presentWorkoutScreenBinding: Binding<Bool> {
        Binding(get: {
            return userDataStore.user.profileData.currentWorkoutID != nil
        },
                set: { value in
            //nothing to do here
        })
    }

    var body: some View {
        
        let nextWorkoutID = userDataStore.user.profileData.currentWorkoutID 

        GeometryReader { screenGeometryProxy in
            let imageHeight = screenGeometryProxy.size.height / 3
            WorkoutsList(workouts: program.workoutsData) {
                ...
            }
            .fullScreenCover(isPresented: presentWorkoutScreenBinding,
                             onDismiss: {
                             }, content: {
                                 WorkoutScreenAdaptor(workoutID: nextWorkoutID!,
                                                      onShowFeedback: showFeedback)
                             })
        }
        .edgesIgnoringSafeArea(.top)
}

struct User: Codable {
    var profileData: ProfileData = .init()
    ...
}

struct ProfileData: Codable {
    var currentWorkoutID:String?
    ...
}

Turns out the problem was on a container to this screen that would cause this screen to be taken out of view and then reloaded.
