Hi, @Callamom , the title of your post suggests that you are having sync issues, but in your post you mention having lost all of your previous history. Please could you give us more information?
Have you recently logged out of your account and logged back in again?
There is always someone here to help, so I am sure with a little bit more information someone will be able to get to the bottom of your issue.
