I've tried playing with this a couple times after updating to the latest... and there are still some issues.

I have a CGEM-II mount with the SkyPortal WiFi.
Raspberry Pi 4 with StellarMate OS and an additional wifi dongle (one connects to home network, one to the Celestron WiFi)
After working around a version issue with libgphoto2, I was able to run update_indi_core and update_indi_drivers.

What I saw was very similar to what Andrew described.

The mount connects and initializes with a seemingly random coordinate; so I sync to Polaris (roughly polar aligned).
The new coordinates look right; If I goto Polaris, it stays put... which is good.
But if I go to any other nearby star, it shoots off somewhere completely different (usually to a position that would damage equipment).

Also, unless I have a hand controller plugged in or go through alignment in SkySafari, there seems to be an artificial stop in one direction of the RA motor.
But, after any form of alignment (through hand controller or app) that artificial stop goes away.
However, I verified this happens when using the manual controls in SkySafari as well, if I have not run an alignment.

I also verified that if I run the alignment in SkySafari, it will then accurately slew the scope to selected targets within SkySafari (so, it can work).
