    <description>&lt;P&gt;Hello.&lt;/P&gt;&lt;P&gt;Our device doesn't have a browser. so I used android webview for OAuth login.&lt;/P&gt;&lt;P&gt;Previously I could sign in to Dropbox.&lt;/P&gt;&lt;P&gt;But I can't sign in to Dropbox today.

      <description>&lt;P&gt;Thanks for the report. The&amp;nbsp;Dropbox web site is subject to change, and only &lt;A href="https://help.dropbox.com/desktop-web/system-requirements" target="_self"&gt;officially supported in the browsers/versions documented here&lt;/A&gt;.&lt;/P&gt;
&lt;P&gt;It sounds like the&amp;nbsp;Dropbox web site is now using a JavaScript feature that the webview you're using doesn't support. (Based on the error output you shared, it appears to be the "Set" object.)&lt;/P&gt;
&lt;P&gt;&lt;SPAN&gt;Unfortunately, that version of Android, and accordingly the browser engine in its web view, is old, from around 2013, and isn't&amp;nbsp;&lt;/SPAN&gt;&lt;A href="https://help.dropbox.com/desktop-web/system-requirements#web" rel="noreferrer" target="_blank"&gt;officially supported by the Dropbox web site&lt;/A&gt;&lt;SPAN&gt;. That being the case, I'm afraid we can't offer help for it. I highly recommend updating to a supported browser version.&lt;/SPAN&gt;&lt;/P&gt;</description>
