"the whole system recently became quite unstable. I just canceled an imaging session because multistar guiding, mount control and autofocus ran havoc."
This. I use the AAP and when it works I love it but when it doesn't you won't be getting anything done. Like this past weekend, after waiting for several months for a clear Saturday night, I took it to my dark site. The AF never worked that night. It would take my nearly focused stars and blow them up to 25fwhm and would never come back down to earth. Tried it at least five times. Luckily I took my Bahtinov mask with me and focused manually to finish that target. The time before that I could not get a connecting to it. Then the ongoing issue that it will only connect to my home network in roughly 1 out of 10 nights, just says my wifi password is incorrect.
Also, the lack of third party hardware support from ASIAIR is irritating, especially when ZWO doesn't offer an alternate product i.e. rotators, high-end focusers, ect
Not sure what mess you ran into but I'm super glad I took my laptop with me and was able to image the rest of the night with NINA. It's just a matter of hooking up the USB cables and hitting connect. It always works and you can run it barbones or with as many bells and whistles as you'd like.
