I'm having the Meridian counter not updating using OnStep, but with the nightly build on Ubuntu (not StellarMate).
The problem seems to occur when Tracking is turned on.
When Tracking is OFF, the Coordinates RA and LST update every second.
When Tracking is turned ON, the Meridian Flip counter updates but then doesn't change. I would then expect AZ and ALT to update frequently, but no Coordinates change.
