I have an issue while unlocking the app from Single App mode. Device Dock is popping up on top of my app and this is disturbing the experience of my app.

I have already done MDM configuration and the indented functionality is working fine with the below code, the app is successfully switching to single app mode and back.

The sample code below reproduces the issue.

Tap on Lock, the completion blocks returns true and the app is successfully switched to single app mode.

Now the device dock is popped up on top of the app.

struct LockApp: App {
  var body: some Scene {
    WindowGroup {
      VStack {
          Button("Lock", systemImage: "lock") {
              UIAccessibility.requestGuidedAccessSession(enabled: true) { success in
                  print("App has been locked", success)
              }
          }
          .buttonStyle(.borderedProminent)

          Button("UnLock", systemImage: "lock.open") {
              UIAccessibility.requestGuidedAccessSession(enabled: false) { success in
                  print("App has been unlocked", success)
              }
          }
          .buttonStyle(.borderedProminent)
      }
   }
 }
}

Is this intended behaviour? Has anyone come across this issue?

I have seen a similar issue with my app. This also reproduces when ending the regular Guided Access session.

Looks like this issue was introduced somewhat recently, maybe during the iOS 17 lifecycle. Have not seen it previously.
