Sharepoint online app installation error
<p>I am working on SharePoint add-in. All works fine but few days ago I have got this kind of error/warning "Your tenant administrator has to approve this app." It happen when app deployed and you have to choose "Trust It" or "Cancel". Trust button is not active. Also I have tenant admin rights.</p>

<p>Here is a pace of AppManifest file.</p>

<pre><code>&lt;AppPermissionRequests AllowAppOnlyPolicy="true"&gt;
    &lt;AppPermissionRequest Scope="http://sharepoint/content/tenant" Right="FullControl" /&gt;
  &lt;/AppPermissionRequests&gt;
</code></pre>

<p>Maybe I need to set rights somewhere else to solve this problem?</p>
