When implementing Inbox Messaging using MarketingCloudSDK iOS (v8.0.7), I have observed that when a Contact installs the app on a second device, previous sent messages are not available on the new device. For example:

  1. User installs app
  2. Device is registered for ContactKey
  3. Send inbox messages to device
  4. Messages are received in mobile app
  5. User deletes app and re-installs, or installs app on a second device (e.g. tablet)
  6. Device is registered for same ContactKey as per step 2

Result: Previous inbox messages are not available

Is this expected behavior? And if so, what is the solution to retrieve these messages?

Working as expected. Sends are device specific and device identifiers do not persist an uninstall.

See your account representative regarding per-contact Inbox messaging.
