Its good to see I am not the only one with a location definition problem. I downloaded the latest version of the app from the SkyWatcher site (and not the play store which is an older version) to a Samsung S20plus and the location finder does not work and the app crashes. I have Android 12 on this machine. I have added local location data manually and the app doesn't crash as a result. Strangley I also loaded the same version of the app onto a Samsung Galaxy Tab S6 with Android 11. The auto location definition works fine. Bloody android systems!!
Hope someone comes up with a work around that doesn't involve setting location manually.
