rjakobson Where do I find "App->About->Feedback"?
There is an icon that looks like a large ellipsis [three dots ...] at the far top righthand corner the main window of the ASIAIR app. Tap on this icon and you should see the "About" window.
One of the items in that window is "Feedback," with a green "Submit" button. Tap on that button.
As to your original question, did you try manipulating the slider that is under the up, down, left and right arrow buttons? That is the slew speed slider (leftmost is slowest slew speed, rightmost is highest speed of your mount). If it is set to less than 8x sidereal rate, it will be slewing so slowly that you may not notice the mount move; see if you can test it with the slider closer to the right.
