I was able to resolve the issue. The app I'm developing has the requirement of working inside of teams and as a standalone website. When running in teams the application is using the Pernille-Eskebo/teamsfx-react library. Outside of teams it is authenticating with the azure/msal-react library. I was using context.app.host.name to determine what authentication to use. Turns out classic teams and new teams have a different host name.... 🤦:male_sign: Thank you for your help.
