Hi there @Heartleader
Sorry for the delayed reply, first thing first, could you also please include the following, this is important when submitting issue with plugins, thanks.
ANA 2 Plugin version
Operating System & version
Using ANA 2 64 or 32 bit ?
There's a known issue about ANA 2 not recalling automation in Live, but once you've clicked on Live's "Re-Enable" button all ANA 2 automation lines should be activated again ( stop being greyed ) and that should not prevent you to hear them. That's for ANA 2 automation.
Now reading your post, are you reporting that this is affecting other automation that you have on the track where ANA 2 VST is inserted ?
