I will set up a run again with meridian flip enabled and post a log.
On the telescope tab, time to meridian is a positive number counting down to zero. As soon as I check the “use auto meridian flip” box in the control panel, the time to meridian just shows “NA”
I did a test (without auto flip enabled) where a target stops just prior to meridian with a duplicate target starting just after meridian. I checked “slew to” for the second, duplicate, target and when it reached the correct time SGP started the slew, and since it was on the other side of the meridian, the mount flipped. In the iOptron ASCOM driver, the reported pier side went from “East” to “West”.
