Skysafari 6 Pro version: 220.127.116.11
I've ran into this same problem last year. Haven't had it reoccur until last night, i.e., couldn't manually align (pointing error, not solving, and then freezing). When the app hangs up, you can not cancel out...just freezes with the gear-thing spinning. The only way out of the app was to reboot the iPad. Anyway, rebooted, and the same thing happened again. FYI: went to Skyportal and it worked just fine.
I can't exactly remember, but I think the solution in the past was to delete Skysafari and re-install it. Is this the only fix I can try or do you suggest anything else?
