Per the title, I have a couple issues with the v6.4.1 update to Commander.
First, sidereal time does not seem to match actual time. I have therefore been unable to properly slew to or plate solve in NINA. When I try and use the mount panel to slew to something in the eve, i.e. Jupiter, it claims it is below horizon ( or some similar warning) and fails to slew. I have of course confirmed I see Jupiter above the trees. Also, probably related, the meridian flip is listed as 24 hours away. When I sync time to PC, it properly resets to my local time and an offset of -480, seemingly correct for Los Angeles. However sidereal time is still "different".
The second problem I have seen reported elsewhere, that the time resets to a random date and time in 2017, and nowhere need my time of day.
One note. As I never use it, I did NOT bother to upgrade the firmware on the hand controller. I have never used it in two years (ish) since the purchase. It is not connected to the mount.
