Did you give permission for ASIAIR to access Locations (iOS location services)?
Go to iOS Settings, scroll the left hand panel down all the way until you reach the app settings. Look for ASIAIR app in there. Tap on it and the ASIAIR setting should appear on the right panel of the screen.
For Location, allow ASIAIR to access "Location" at least "While Using." The other one you need is to let ASIAIR access "Local Network."
