Enfold Theme does not update from WP Dashboard due to Envato API malfunctioning.

Hi all. I manage several WP sites running Enfold, I’ve always update the theme from dashboard by checking the version using the Envato API. I’ve asked to Enfold Support and they answers that the malfunctioning is due to Envato API fail as described in this post: https://kriesi.at/support/topic/auto-and-manual-update-to-4-2-1-doesnt-run/

Did is possible to fix avoid to proceed with a risck FTP update…?
