You have some answer in other posts about issues with Star Adventurer...
I think they only connect the SA after the PA is done. Manually rotating the mount.
SO ASIAir when starting page shows, should not have a mount selected.
Only after PA is completed you connect the ASIAIr to the mount, go into the Mount tab to select and connect your SA then...
If I remember correctly... but you'd better find the right post.
