We are currently investigating issue with some syncs failing with mismatch errors.

We experienced a performance issue from ~3:00-3:15pm Pacific that may have caused some syncs to fail with a message about "mismatch counts". We believe we have resolved the problem, but syncs that encountered the issue may not report an error until sometime after the fact, so errors may continue to trickle in. If you encounter this error, please attempt to rerun your sync. If a rerun does not succeed, please contact support.
