It has come to our attention that iOS update 8.3 is unable to receive GPS data from Cygnus Pro Wireless and Cygnus Home Direct. In combination with Bad Elf, our engineers were able to determine that all accessories that use Apple’s 30-pin connection protocol are no longer able to correctly forward location data. Bad Elf has posted a similar notice on their blog. This also affects other 3rd party apps that use location services, such as ForeFlight.
Update (Tuesday 30-June): With the release of iOS 8.4, the bug that prevented most GPS accessories from providing location data has been fixed. Redbird Cygnus customers experiencing issues with iOS 8.3 should update to iOS 8.4.
