Azure Sign-In Error Code 50140

While troubleshooting an issue recently, I noticed failures showing up in the Azure Sign-In Activity panel with a sign-in error code 50140.  The error code gave the following details:

Failure reason

This error occurred due to ‘Keep me signed in’ interrupt when the user was signing-in. Open a support ticket with Correlation ID, Request ID, and Error code to get more details.

This was happening for a variety of single-sign on enabled applications.  Upon testing, the user logged in and was prompted with KMSI as expected.  They experienced no trouble either when selecting Yes or No to the prompt.  After opening a case with Microsoft, and reaching out to someone on the inside, both confirmed that this was more of an anomaly in the logs and could be safely ignored.  It sounds like this will soon either be resolved or changed to an Informational message instead.
