Hello @dwoodwar
Thank you for reaching out to the Community regarding your issue, although I am sorry to hear that you are experiencing with synchrony. While you might not be getting the error specifically it is likely you're still being effected by the error from the sound of it. I would recommend following the synchrony thread for any further updates.
