sorry to hear it still does not work for you! I can confirm about the extra steps i forgot to mention (ASIAir wants confirmation that mount can not be detected) – it's the same over here, just forgot to write it down from memory in my last post. And yes, before starting to loop in the guiding view, i make sure that it's RA only and DEC is off, too. For aggressiveness, i still use the default values (never touched those).
As noted in the edit of my last post, I use the the ASIAir app versioned
1.5-6.76 and Firmware
1.5, both are the latest official release from last month. Actually, i don't know which firmware my SGP has installed. I bought it in 2019 and never updated it, because i thought it would be the latest firmware as the last release from iOptron was in 2017.
