"Thanks for your email and report. Unfortunately, These are known issues with Auto-Align Post and other ARA2 plugins in Nuendo. Steinberg is aware of this and we hope it’ll get resolved soon. If you’d like, you can write Steinberg and ask them the fix these issues. "
It basically works but with some limitations.
Upon enabling the ara extension nuendo bounces the audio events, thus you loose the handles, metadata and dop history.
A workflow may be possible. Say you duplicate the boom and lav tracks, sync the copy with boom as reference and delete the duped boom track.
You now have a synced lav track to the original boom. You loose the handles for the lav’s but still have the original to patch in if needed.
