So my series 4 sssb has been stuck on installing 5.1 For an hour and a half now with nothing showing on the watch except the bright white Apple icon. Spoken to Apple Support who said that they are getting calls from other people experiencing the same issue and they have advised me to leave it for 2 to 3 hours. WTF Why would an update that supposed to take 10 minutes to install take 2 to 3 hours
