I have this exact same problem as well. Based in Sydney, Australia, I only have a north facing view of the sky from my balcony (my apartment building obscures to whole south facing aspect) and ASPA would be super useful (in fact I had clear skies and a great view of Andromeda last night but couldn't PA!). Same symptoms - if I just refresh the screen without adjust RA or DEC at all, the values just keep increasing in both directions. Trying to adjust for DEC and RA is a fool's errand.
I have my fingers crossed this issue will be fixed in the beta release - @Tech@ZWO, do you know when this is scheduled to be released?
Thanks.
