Hi,

We’ve used auto-update platform from WP-Updates: http://wp-updates.com/ ( It’s a paid service from a third-party company - not from us ) and it seems the updates flatform from them has issues and they didn’t fix it.
We’re waiting for some weeks but they didn’t fix the issues, so maybe in the next updates, we will remove this flatform.
And from now, please do follow this guide to update this theme – It’s easy also and doesn’t affect anything to your site:

We’re sorry about this inconvenience.

Best Regards,
