We have checked the documentation, and it is documented here:

Hello, Community.
We've built a Teams tab app following pretty much this sample https://github.com/OfficeDev/TeamsFx-Samples/tree/dev/hello-world-tab-with-backend
It is working fine on all platforms (Teams Web, Teams Desktop, Teams Mobile, Outlook Web, Outlook Desktop) except Outlook Mobile. It seems that outlook mobile is not getting sso token from:
import { useTeamsUserCredential } from '@microsoft/teamsfx-react';
We're getting this on Outlook Mobile:
My understanding is that the Auth flow should work exactly same on all platforms

Could you please refer this sample:
https://learn.microsoft.com/en-us/microsoftteams/platform/tabs/how-to/authentication/tab-sso-troubleshooting
Please ensure that the Microsoft Authenticator app is properly configured and that the user is signed in.
Please ensure that the Teamstab application is registered in Azure AD and that the correct permissions are granted. -

We've thoroughly checked and all mentioned aspects are configured properly.
Just to recap everything is working on all platforms (Outlook, Teams, MS365) Web/Desktop and mobile except just Outlook Mobile (iOS/Android). It seems that it expects fundamentally different auth flow. I've tried, but couldn't find any related documentation. And I also see a lot of other threads where other developers are complaining about the same issue, but none of those have the solution.
My understanding is that all those platforms should follow same rules.
Thanks

I was able to fix the issue.The problem was because I didn't have Outlook Mobile client Id in my app registration, and in backend configuration. For some reason it was not included in the official template
