Overbridge 2 no sync or audio in Ableton

Overbridge 2.0.31.1 no sync or audio received at the plugin in Ableton using Analog Four MKI.
Works perfectly in Logic Pro X.
Works perfectly in the standalone app.
Audio works when selected as a soundcard in Ableton.
Midi/Sync also works in Ableton when USB MIDI mode selected on A4
Analog Four is being recognised by Engine/plugin.
I have tried both AU and VST.
I have tried uninstalling and reinstalling Overbridge
Using Ableton 10.1.4.
Analog Four MkI OS 1.40A
Mac OS High Sierra 10.13.8

Any suggestions?
