Some two weeks ago we were moved to the new Sync functionality. The new functionality offers an option to define a different Opt Out checkbox than the Email Opt Out. This is a good improvement since opting out from a Campaign Newsletter is not the same as opting out from personal email communication from Recruit. However, the functionality does not work. I have reported this 12 days ago. You took away the option to configure a separate field, but we have not seen any solution. I just tested to Opt Out again, expecting at least the Email Opt Out field to be in operation. It did not work.
