You setting on the H9 side seem fine, given your Algo is looking for tempo.
You did mention you had updated.. so I ~assume~ you are on the latest version.
I am on version 18.104.22.168.. so the theory is the Update broke MIDI clock. Notably, I havn’t run MIDI clock in a while, and I tried recently and failed. I maybe didnt hook it up right, so I am going to test again.
I get successful clock using a generic USB cable and MIDI-OX. So the update ~itself~ is not broken. Could it have mis-installed? Maybe. In that case a reset might help. Might it be on the Ableton side? Maybe. Can you send clock from a different program to test?
