When it’s “ON Synchronization” originally it should be translated as “mit/während Synchronisierung”
You’d have to take that up with @cgrunenberg (who is German).
although it’s “after synchronization” actually, isn’t it?
Not necessarily. See this smart rule…
Does that trigger before the sync or after? It’s unclear without seeing the action, but the result is the same. If there is any useful distinction, Development would have to clarify that.
