Hey @pbabcock
Thanks very much for using Codebook and reaching out, although I’m sorry for the trouble you experienced during sync. We’ve responded separately to your support request which I believe has resolved the issue for you. Because many factors can come into play depending on which devices and sync providers are used, we feel that it’s better to handle this on a case by case basis with guided support rather than publishing a blanket set of steps (which may not work for every case).
There are some improvements coming in the next release of Codebook which should both prevent the issue you experienced from occurring and allow recovery to be greatly simplified. There’s a link to sign up to test the next version within the discussion post above. We should begin external beta testing shortly.
