I updated to version 2.0 on one of my sites today and it's completely broken.
It seems to not read the old version's OPTIONS so your CDN keys are lost and have to be re-entered.
When I run the "Sync Now" tool, I just get a TON of database errors and no actual sync takes place.
Glad I only updated 1 of my sites and can revert it soon.
Hopefully this gets fixed soon. I've sent a support email to the developers.
