I am in record A of couple who both have individual records. Have a home address update to add. So, click to change preferred to alternate and add the new address as preferred. When asked if I want to update the other records sharing this address, it's a spouse so of course I do. So, click yes. When I go to record B, the only address listed is the new preferred one. Previous address is gone. I've lost my address history for spouse B. Unacceptable. One of the advantages in RE is that a record can maintain address history/more than one address. Totally lose that ability with this situation.
Per BB support: "the only way around this behavior is to choose no and add the address to the spouse manually."
