Social Sign-In Not Completing

Quick Setup

Most fixes take under 2 minutes. You can try them on the login screen.

This guide helps you finish social sign-in when the login page does not move forward.

AVA Portal mobile shell

If you use AVA Portal on mobile, Google and LINE use an app handoff. Let the app reopen Streamliner, then finish sign-in there.

AVA Portal mobile shell handoff does not finish​

Fix:

  1. Wait for the provider step to finish.
  2. Let the app open the Streamliner login page automatically.

No browser fallback

The mobile callback does not continue to a browser login page. Use Return to AVA or restart the social sign-in flow.
