Custom Teams App not loading under macOS
Microsoftnautalis - Could you please let us know if it is happening in Teams Classic or New Teams? Also, if it's happening in Teams desktop or web client? Please do share the manifest file as well which you are using.
Prasad_Das-MSFT The issue is happening on both Teams Classic and New Teams on all deployed macOS laptops. The custom Teams app works fine through web client on macOS. The custom app is installed via app policy. The custom app does not present any error windows, messages, or feedback. When clicking on the custom app, all the user sees is a blank white screen in the right-hand pane. What the user should see is the organization's intranet SharePoint site.

nautalis , besch415 - We got update from engineering team that "SharePoint hosted apps must use TeamsLogon.aspx and correctly configure the webApplicationInfo section in the manifest in order to handle authentication correctly." There is a great blog post explaining that here:
https://bob1german.com/2020/01/06/teams-apps-with-sharepoint1/It should be important to note that these types of custom wrappers around SharePoint are not officially supported. The only supported way to integrate SharePoint content into Teams is either via one of the built in apps like Viva Connections, SharePoint, SharePoint Pages, Lists, etc. as documented here:

Or using the SPFx framework:
