Steps to Replicate:
- Log into the Blackboard app with an account that requires Duo 2-factor authentication
- Request a Duo 2FA push notification
- Accept Duo 2FA push notification
The Blackboard app loads the User's account
Observed Behavior:
The Blackboard app remains on the Duo 2FA screen with a session error message

Cause: This issue only affects iOS 11 devices. There was a change in iOS 11 UIwebView which causes requests to be terminated when put in the 'background'. So, when bringing the Duo app to the forefront to approve the pending authentication transaction, the request being approved in the background is lost. Older iOS devices and Android appear to work fine in most configurations. However, as this is not an officially supported feature of the Blackboard and Instructor apps, Bb does not yet guarantee this functionality.
Resolution/Workaround: Workaround - Use the Duo passcode option.
Resolution - This issue was resolved by iOS 12
Target Release: Future Reference
Patch Available: No
