HI Morkus, There is not a way to find out except trial and error at the moment. One thing to note is that all of the data that was last synced is still local if no changes to the local profile have been made. In this case, creating a new profile with the email might be an alternative. Keep in mind if this is not the case, changing the password will prevent syncing old data to a new profile. Sync uses end-to-end encryption; if you change your password, you can't recover your data. I am sorry I could not be more helpful.
