Just spoke to support and they have no record of the update being pulled but i have two SS series 2 watches and the first one updated cleanly but slowly. The second watch is telling me that 3.,1 is the latest update so yeah they have pulled it
I was blissfully ignorant of any issues and updated my AW2 to 3.1.1 earlier today. Thankfully it went smoothly. I must have gotten it downloaded and installed before they pulled it. I haven't updated my AW0 yet so I guess it can wait.
