Teams static Tab App not working in new Teams.

I've developed a react application that works as expected in classic teams.  I can run the application locally using Teams Toolkit with no problems.  I have also deployed the application to the teams Developer portal and published it to my organization.

 

In classic teams it works as expected, opening "New Teams" and then navigating to the same app does not load. There is no loading indicator, no error message, just a blank screen.

 

A possibly related issue is opening the app in mobile results in an error "Something went wrong, and we can't open the app right now"

 

How do I troubleshoot this?  Is there a way to debug mobile or "New Teams"?

    Hello MrTimn - Thanks for raising your query.
    If you are trying it from personal 1:1 chat, most probably it's a known bug in new Teams but still we will verify it once again and let you know the updates.

    Could you please share the below details:
    Teams Desktop Version
    iOS/Andriod version including Teams client version:
    Manifest
    Any other specific details so that we can easily be able to repro it.

      Version Information from teams Desktop:
      You have Microsoft Teams version 23257.2616.2423.5046.
      You've got the latest version. It was last updated on 10/6/2023.
      The client version is 49/23091420217.

      Android version: 13
      Android Teams Client:
      Version: 1416/1.0.0.2023173501/0925
      Calling Version: 2023.31.01.1

      I'll try and send the manifest as a direct message.

      The application is a teams static tab application. The origin site is a standalone website that uses teamsfx-react(^3.0.0), teams-js(^2.13.0), and teamsfx(^3.0.0) to authenticate while the application is running in teams. When the site is loaded outside of teams it uses azure/msal-browser for authentication. It's a react app that GETs and POSTs to a private API. Both client and API are App Registrations in Azure AD/Microsoft Entra ID.

      Application runs in teams classic, and standalone outside of teams. New teams shows a blank screen when opening the application, no error message, no indication at all that the site was loaded.
