When attempting to view ERR signatures in the View App, when clicking the Proof of Delivery tab, the message "Failed" appears.
The user that is signed in does not have permission to the USPS ERR account that received the signature.
- Sign in with a user that has access to ship with the USPS ERR account under which the signature was processed.
- Open the View App and download the signature for future use.
