404 Not found when trying to use Teams SSO to get the user token about botframework-sdk

I'm having the same problem when using the Emulator, the sample codes are not working because the GetToken endpoint is returning Not Found, so it is asking for authentication on every turn.

We are seeing the same issue, any pointers on what can be done to mitigate this?

@sandeepvootoori I got it fixed by asking the users to use the bot for the first time via the new teams client. The old client was the culprit

We are having the same problem. Got any progress update?

@brnowakowski not had any more information from Microsoft, they said they were 'tracking' it but yea I guess nothing will happen. You need to make sure people are logged out and use the new teams client to do the authentication first.
