I installed and have a Sync Now item under Tools, but nothing happens when I click it. There is no message or any delay at all. When I open Add-ons > Extensions and click the EverSync preferences button an EverSync page is momentarily displays (less and a second) and then the top level Add-ons page is shown again. I tried uninstall and re-install, but no change. How do I fix this?
