Describe the bug

When sideloading bot in group chat, I'm seeing error {"errorCode":"WebApplicationInfoIdOfSideloadedAppMustBeInTheSameTenantAsUser"} for request URL: https://teams.microsoft.com/api/apps/part/msft/beta/chats/redacted/apps/definitions/appPackage

webApplicationInfo was added to the manifest.json due to error:

{
    "errorCode": "UnableToParseTeamsAppManifest",
    "message": "RSC permissions require webApplicationInfo.appId to be configured in the manifest. The manifest includes resource‑specific consent permissions, but no appId is defined under webApplicationInfo."
}

After adding webApplicationInfo, the bot works fine in personal chat, but not group chat.

Expected behavior

Bot is added to the group chat successfully. These errors started in recent weeks.

Screenshots

The error is displayed as "Something went wrong" in Teams.

Additional context

• Bot uses user assigned managed identity
• manifest.json contains RSC permissions

  "authorization": {
    "permissions": {
      "resourceSpecific": [
        {
          "name": "ChatMessage.Send.Chat",
          "type": "Application"
        },
        {
          "name": "ChatMessage.Read.Chat",
          "type": "Application"
        }
      ]
    }
  },
