Answer 1

Have you made any schema changes recently? Any change on the database schema of the hub database or any member database should be manually propagated to all other databases because SQL Data Sync does not support dynamic schema changes. Changes to schema include: changing the name of indexes, columns and tables; adding objects, indexes or adding columns to tables. Take in consideration that changes to server names are not supported too.

Make sure primary keys are not getting updated because is not supported.
