SwiftUI DragGesture not called on ZStack on iPhone 12 on iOS 16.3.1

I have an app written using SwiftUI that uses a ZStack with a DragGesture handler. That handler doesn't get called on some phones on some versions of iOS. For example, iPhone 10, 12 & se work as I expect on iOS 15.x, but on iPhone 12 on iOS 16.3.1 & iPhone 13 on iOS 16.5, the gesture handler is not called. I've used .onEnded & .updating, but the problem persists. Code is as follows

        ZStack {
            Color.detailScreenBackground
                .ignoresSafeArea()

            VStack(spacing: 20) {
                viewModel.image()
                    .resizable()
                    .scaledToFit()
                    .frame(width: 88, height: 88)
                    .clipShape(Circle())
                    .overlay(Circle().stroke(Color.gray))
                    .padding(.top)

                Text(viewModel.name)
                    .font(.system(size: 40))
                    .fontWeight(.semibold)

                viewModel.connectionStateView()

                VStack(alignment: .leading, spacing: 20) {
                    HStack {
                        Text("Model")
                        Spacer()
                        Text(viewModel.model)
                    }
                    .padding([.leading, .top, .trailing])

                    Divider()

                    HStack {
                        Text("Serial number")
                        Spacer()
                        Text(viewModel.serialNumber)
                    }
                    .padding([.leading, .bottom, .trailing])
                }
                .background(Color.white)
                .cornerRadius(cornerRadius)

                VStack(alignment: .leading, spacing: 10) {
                    firmwareView()
                        .background(Color.white)
                        .cornerRadius(cornerRadius)

                    Text(viewModel.webPortalInstructionText)
                        .font(.caption)
                        .padding(.leading)
                }
                
                Button(action: {
                    router.push {
                        DeviceSettingsViewFactory().viewFor(lock: viewModel.lock, tenantLogicController: tenantLogicController, router: router)
                    }
                }) {
                    HStack {
                        Text(viewModel.settingsText)
                            .padding()
                        Spacer()
                        DisclosureIndicatorView()
                            .padding()
                    }
                }
                .background(Color.white)
                .cornerRadius(cornerRadius)
                .disabled(viewModel.connectionState != .connected || settingsTapped )
                .foregroundColor(viewModel.connectionState == .connected ? .text : .disabledGray)

                Spacer()
                
                syncButtonView(lock: viewModel.lock)
            }
            .padding([.leading, .trailing])
        }

        .gesture(DragGesture(minimumDistance: 200, coordinateSpace: .global)
            .updating($dragOffset, body: { value, _, _ in
                // Swipe right
                if value.location.x > value.startLocation.x {
                    disconnectAndGoBack()
                }
            }))

Am I doing something fundamentally wrong?

Thanks
