Before we turn on relationship editing, we need to solve several data integrity issues. Family Tree is a new system with a new database. To populate this database, we migrated all of the people and their relationships from new.familysearch.org (nFS). There is a mechanism to keep these two systems loosely in sync.
This sync mechanism currently has several defects that result in the Family Tree data becoming inconsistent. The most serious defect occurs when users combine people in nFS. When that combined person is synced to Family Tree, the combined person remains as two people. This causes unexpected results as you navigate your tree.
Before we turn on relationship editing, we need to correct this problem. It's very important to note that once we turn on relationship editing, the two systems (nFS and Family Tree) will diverge. You should not expect that the two systems will display the same data. You should focus your attention on Family Tree. Correct the information there. Personally, I have stopped performing operations that separate and combine in nFS. (You Should Too!!!!!)
We are taking this problem day by day. It may require a planned outage to correct. We hope to have this fixed and turned on soon. Stay posted.
