I have set up the two-way sync between Google Cal and Doit.im through the preferences page on the Web interface. Yet when I click on the "G" in the upper-right corner I get the following error:

"You haven't selected to sync to Doit.im yet.Please sign into Doit.im for web and select in Preferences."

I've double-checked that in Preferences it tells me that the two-way sync is established.

Please help resolve this.

Thank you,
David
