The symptoms: sometimes Auto Stop is not triggered at the end of a given flight, and/or the next flight gets concatenated to the previous.
The first CloudAhoy user to report the flight concatenation bug was Abram Dancy, back in March 2012 (the name is used with his permission). Abram’s bug reports, and other users’ reports, resulted in app version 1.8. But it turned out that another fix was needed. Hence app version 1.9, in the iTunes store as of today. Thanks to every user who reported a problem!
