I've changed to "KStars updates all devices".
Three times in a row the same thing happens, that is when the target hits the meridian Ekos stops tracking (mount is set to stop when HA > 5 and Ekos flip when HA > 2 degrees).
Please see the attached logs. All shows 'Mount status changed from "Tracking" to "Idle"' when the target hits the meridian.
Please let me know if there is any other setting you want me to try out.
