The issues seem to be different, the TSX issue is that SB have removed sync from their scripting, at least for SB mounts while the issue with Celestron with StarSense if that the scripting command in the StarSense HC doesn't work properly.
I know it's a nuisance, and may seem like a waste of time, but PLEASE make a fuss about the StarSense issue with Celestron. While they ignore what their beta testers say they do seem to pay attention to multiple issues raised through support. Ideally get the dealer's attention. This is what worked with getting them to fix the polar align function in StarSense. The best way to do all this is to hit them where it hurts - by returning StarSense and asking for your money back.
