Description (partial)

When attempting to login to the Webex Teams Android client, the user receives a popup stating:

"Potential security risk. The SSL certificate provided is not from a trusted authority. Please contact your IT administrator."

The user is unable to bypass this popup and cannot login.

The Android client logs may show:

X509Util: Failed to validate the certificate chain, error: Trust anchor for certification path not found.

All of the following are true:
1. The user is using the Webex Teams Android client
2. The organization is configured to authenticate Webex Teams users using Single Sign On (SSO)
3. The organization's SSO Identity Provider (IdP) either: 
a. uses a self-signed certificate on the login page or 
b. the IdP is using a privately or publicly signed certificate where the entire certificate's trust chain is not present on the device
