Hello everyone,

I have a legacy web app that is hosted locally and published via Entra ID App Proxy, ensuring it is secured by conditional access policies. I wanted to test its integration in Teams, and it works fine as a custom app. When I call the “Entra ID App Proxy” app within a custom Teams app, it functions seamlessly with SSO on the Teams app for Windows and in MS Edge.

However, I encounter an issue with SSO when I open the custom app in Microsoft Teams (version 6.18.2) on iOS (version 18.0.1). It always prompts for credentials (username, password, and MFA code), which is different from my experience on Windows and in the browser.

Has anyone else tried something similar to make a legacy app available within Microsoft Teams? Any insights or solutions would be greatly appreciated.

Thank you!
