I build a a Teams App via Developer Portal, which allows me to add a Tab to a Channel. The TabConfiguration is running on a external webserver with SSO via Microsoft Azure enabled.
When i open Teams in the browser or the android app i can select the tab, it will automatically authenticate with the azure user which i used to log into teams and show me the content of the webapp.
When i open the windows app (tried on multiple windows computers), the tab does not show any content at all. When i open the developer console for the teams app i receive the following errors and it does not send a network request to the webserver.
Unrecognized feature: '{{(ctrl.frame'.
The Content-Security-Policy directive 'prefetch-src' is implemented behind a flag which is currently disabled.

Can anyone help me with this?

Have you followed the prerquisites for tabs? -

The “office-teams-windows-itpro” tag is for general questions about Teams client. Since your question is related to developing Teams application and the “office-teams-app-dev” tag which is more appropriate has already been added, I’ll remove the tag “office-teams-windows-itpro” . Thanks for your understanding.

yes, i checked that. The app i created has this options set. It can be displayed in browser, on mobile AND on desktop, as long, as SSO is disabled. From the moment i enable SSO, i am being sent to some microsoft login page that (at least on browser and mobile) automatically sends me back to my app being authenticated.
I dont get, why the microsoft login page for sso wont allow being displayed as an iframe in the desktop version, but works fine on all other platforms...
Any other suggestions?
