Two-way sync between systems (updating either one updates the other) is dramatically more complex than one-way sync and introduces the risk of sync loops, system A updates system B, which triggers a change that updates system A again, a well-known failure mode that needs explicit loop-prevention logic, not just a naive bidirectional trigger.
In a real workflow

Common mistakes
- Two-way sync without conflict rules.
- Sync loops that update forever.
