title: Microsoft Graph API Activity Feeds Notification does not push to mobile app
body: <p>I'm <strong>POST</strong>-ing to MS Teams Activity Feed Notifications via the Microsoft Graph API. However, the notifications are only being pushed through to the <strong>desktop</strong> and <strong>browser</strong> applications</p>
  <p>With the Microsoft Teams Mobile Application (both Android and iOS),  we are getting either none, or intermittent push notifications, and the mobile Activity Feed is not showing any of our notification items.</p>
  <p>I am using the following endpoint:
  <code>https://graph.microsoft.com/v1.0/teams/{GROUP_ID}/sendActivityNotification</code></p>
  <p>I have the following payload:</p>
  <pre class="lang-json prettyprint-override"><code>{
      &quot;topic&quot;: {
          &quot;source&quot;: &quot;text&quot;,
          &quot;value&quot;: &quot;Relevant Channel&quot;,
          &quot;webUrl&quot;: &quot;https://teams.microsoft.com/l/entity/{APP_ID}/{ENTITY_ID}?context={\&quot;channelId\&quot;:\&quot;{CHANNEL_ID}\&quot;}&quot;
      },
      &quot;activityType&quot;: &quot;userMention&quot;,
      &quot;previewText&quot;: {
          &quot;content&quot;: &quot;App Name&quot;
      },
      &quot;recipient&quot;: {
          &quot;@odata.type&quot;: &quot;microsoft.graph.aadUserNotificationRecipient&quot;,
          &quot;userId&quot;: &quot;{RECIPIENT_AADOBJECTID}&quot;
      },
      &quot;templateParameters&quot;: [
          {
              &quot;name&quot;: &quot;name&quot;,
              &quot;value&quot;: &quot;My Name&quot;
          }
      ]
  }
  </code></pre>
  <p>My authentication token is fine, and included in the headers, and my application has all the required permissions.</p>
  <hr />
  <p>Am I posting to the wrong endpoint, or are there issues around push notifications to the Microsoft Teams application on mobile devices?</p>
