title: PowerApps attachments from sharepoint forms does not work (unsaved status)
body: <p>I recently created my first Power App.
  In this PowerApp i have connect with Sharepoint list. On one of the screens I have an attachment box (with default settings - I haven't changed anything.</p>
  <ol>
  <li>Attachments are allowed on my list.</li>
  <li>Data Card is in a new mode (in edit mode it is not visible).</li>
  </ol>
  <p>So right now I can play this app and this attachment form does have a logic. I can select attachment to add it is is OK. But this attachment has a status UNSAVED.</p>
  <p>And when I save my whole form with attachment with function:
  SubmitForm(Form2),
  The attachment is not saved. It is not visible on Sharepoint List.</p>
  <p>On attachment page I have formula on button:</p>
  <p>SubmitForm(Form1) &amp;&amp; SubmitForm(Form2);;
  ResetForm(Form1) &amp;&amp; ResetForm(Form2);;
  Navigate(Screen4;Fade)</p>
  <p>Form1 is Sharepoint List multiline text
  Form2 is Attachment from Sharepoint List</p>
  <p>Multiline text is saved. All seems good, but no attachments are to be found.
  Do you have any idea how to solve this?</p>
