The admin ui for mapping has a scheduling tab with two sections:
- reconciliation schedules
- sync options
The sync options, however, has a toggle to "Enable Sync" and when it is toggled and saved, a message pops up saying that "LiveSync is now enabled" (or disabled). This toggle changes the value of the "syncEnabled" property in sync.json for the mapping which controls whether this mapping participates in a sync when the source changes.
So the bug is mainly the messaging, but as this toggle has nothing to do with schedules, I'd submit this sync enabled toggle is in the wrong spot.
