We are upgrading the Teams app deployment and cannot complete the update.

We see:

"This app is outdated and needs to be updated before March 31st, 2026"

When sending the upgrade link we get:

AADSTS900971 No reply address provided

SSO is enabled and the Enterprise application exists in Entra,

but login fails during the upgrade flow.

Can you verify the SSO / Teams app upgrade for our tenant and ensure the redirect URI is configured?
