I'm in touch with Alex Lucas @ novation, they can't reproduce the problem but are looking into it.
The last response I had from Ableton was in october.

at the moment it's not completely clear what's causing this issue. We were able to reproduce it but it seems to be a combination of changes on our side and on Novations side. Automap uses a very special way to communicate with the host software. Probably both Novation and Ableton have to change something to make this working again. This makes it hard to tell if a fix will be available, soon.
Ableton Technical Support
I'd urge anyone suffering with this to contact both Ableton and Novation email@example.com@focusrite.com
The more of us that contact them the more likely someone will take notice.
