Hi,

In the past, 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 the updates platform from them has issues and they didn’t fix it.
We were waiting for a long time but they didn’t fix the issues, so in the next updates, we will remove this platform.
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,
PenciDesign
