Sometimes attempting to initialized will show the “Missing Configuration” error. This is likely because the user has entered their email address and pressed [ enter ]. This action will throw the above error every time. The user must *click* the “Save & Write Configuration to Storage” button for the email to be correctly saved. Until the email is successfully saved the UI will remain un-initialized and the user will not be able to proceed.
These fields are not intended to be required. This is a documented bug in 3.1 that will be addressed in 3.1.1. The problem shows up when using Chrome, Internet Explorer, and Firefox browsers. To get around this show *all* advanced options fields and enter [space] into each of the empty fields. Doing this will allow the user to submit a new sync.
