SingleWebPartAppPage not working in MS Teams Desktop Client

Question

Hi Folks,&nbsp;1 ) Created Hello world solution with SPFx 1.8.2 and added to the SharePoint App page (Full SharePoint Page). Then added below parameters and build &amp; packed the solution."supportedHosts": ["SharePointWebPart","SharePointFullPage"],&nbsp;Next added it to the SharePoint App Page. It works perfectly.&nbsp;&nbsp;2) In Microsoft Teams, with App editor created a manifest file with personal tab and added newly created sharepoint page in content URL.&nbsp;3) Tested and downloaded the solution. After installing it to the Teams App gallery and trying it open it from App tray, it is loading SharePoint Page in Teams Tab.&nbsp;When I checked it in web version, its works fine. But not in desktop version.&nbsp;4) To rule out the issue added below domains to render the application.&nbsp; "validDomains": [
        "tenantname.sharepoint.com",
        "tenantname.sharepoint-df.com",
        "tenantname.login.microsoftonline.com",
        "msft.spoppe.com",
        "resourceseng.blob.core.windows.net",
        "spoprod-a.akamaihd.net",
        "spoppe-a.akamaihd.net"
    ]&nbsp;Please correct me, if I'm doing anything wrong in the solution. Here are the screenshots for Desktop &amp; Web.&nbsp;Web: WORKING&nbsp;Desktop : NOT WORKING&nbsp;

Hi&nbsp;Srinivas Narula&nbsp;,&nbsp;One thing you can try is adding another "supportedHost":TeamsTab(See example on&nbsp;https://docs.microsoft.com/en-us/sharepoint/dev/spfx/web-parts/single-part-app-pages).&nbsp;I don't know if this will solve you issue though, it's just something you might try.&nbsp;I have a question though, if you are using a SingleWebPartAppPage, isn't it more interesting to directly add the webpart as a team tab instead of wrapping it by a page and adding the page?More information about this can be found at following location:https://docs.microsoft.com/en-us/sharepoint/dev/spfx/web-parts/get-started/using-web-part-as-ms-teams-tab&nbsp;Hope this helps!
