If you're using Synapse as a child theme, you should see an update to v.2.0 in your control panel. In this release, quite a few things were changed and should not pose any issues, however if you notice anything, please let open a new topic and let us know. A new feature you'll also notice is the new "Mobile Settings" tab. One of the new options were added to enable a fallback mobile header. If you see a horizontal scrollbar on the frontend of your site, this new setting may help you.
