Please review v1.8-8.83 of the app given the number of problems people have had with it. For me, v1.7 worked perfectly with my Skysensor 2000, 120MM mini and 2600MC Pro. The update has caused camera dropouts and completely deactivated the guiding function reducing it to an expensive polar alignment tool. The poorly quality control of the update has cost me 1 week of imaging time trying to determine the source of the problem. The fastest solution to the problem is to make v1.7 of the app available somewhere for those who were happy with it. In the future I would suggest you leave the last version available on the app store until all of the bugs in any new version of the app have been resolved. This would allow users to at least continue to image and not waste their time.
