Why is my place not saved in The Orpheus Device?
Sorry, but Google Assistant on the Android surface does not allow developers to retain user data for persisting save states across sessions.
You can use Google Assistant on all other surfaces (Home, Mini, Hub, Hub Max) to save your place and return where you left off in the previous session.
Note that you can play the story on Android with Google Assistant, but if so your place will not be saved when you exit the session. Playing a new session will start the story over at the beginning each time. You will receive this notification if you use Google Assistant on Android.
