Motorized faders not following automation in Live 12 (works in Live 11) with same script

Hi,
I’m using custom Remotify scripts with my Behringer X-Touch Compact. Everything works perfectly in Ableton Live 11: motorized faders follow automation in real time.

However, in Ableton Live 12 (with the exact same scripts and MIDI setup), some faders no longer move during automation playback. They still update correctly when I switch tracks (e.g. after the automation has finished, if I change to another track and back, the fader jumps to the right position). But they don’t follow the movement continuously during automation playback.

So it looks like Live 12 only sends snapshot values, not the continuous updates.
Has anyone else experienced this? Is it a known limitation/bug with Live 12 or do I need to update/regenerate my scripts in Remotify?

Thanks!
