Hi,
the European summertime is set active but not recognized in Skysafari 6 Pro, Plus and the also the free version on my Samsung Galaxy 9 Plus, same issue on my Samsung tab. The correct time is shown in the settings but 1 h less is shown at the main screen. I also use the Celestron SkyPortal App which does not have this problem. If it would help to fix the issue I could provide you screenshots. Thank you.
