When multiple users attempt to access a Unifier environment via iOS iPhone they are seeing the error noted below and/or it is taking more than a minute to complete the login process.

"Error System error. Please re-try your action. If you continue to get this error, please contact the Administrator."

If or when the users are finally able to log into the mobile application, they find that they are not able to Add any Business processes when clicking the “+” tile in the mobile device. It keeps spinning and nothing happens

With an Android phone the users are unable to log into the Unifier environment via the latest mobile application (20.7), and the phone only displays a blank white screen.
These issues began after an upgrade of the Unifier environment servers to Primavera Unifier version 19.12.6. All Mobile devices being tested were at either Unifier Mobile application iOS version 20.7 or Android version 20.7.

The issue can be reproduced at will with the following steps:

  1. Use QR code to load URL to Mobile application.
  2. Set SSO on > Authenticate
  3. Enter user Credentials.
  4. User receive the error noted above (iOS) or the blank white screen (Android).
  5. If the iOS users should be able to login after a long wait, they find that when clicking the "+" tile, they are not able to add any Business Processes.
