On my wife's watch she forgot to update to beta 5 on her watch. With the quick turnaround to beta 6 this week I told her to hook it up and upgrade. Well we get the same error every time... Unable to Install Update An Error occurred installing the latest version of watchOS 3 on your Apple Watch I've deleted the profile and reinstalled it...restarted each device multiple times with no luck. It seems to me that its related to the fact she has beta 4 instead of beta 5 on the watch. Guessing there is no way to install beta 5 first? Help me Obi Wan Kenobi you are my only hope.
