Same for me. When looking for update, AW said: no update. Then I did a search in the AppStore on AW and was able to update the app. Now on 4.4.39 on both devices and already paired my Stryd.Thanks so much!! Really very, very excited!!!
Just updated iPhone version to 4.4.39 via the iOS App Store Germany and it didn't update the Watch app automatically. I then went to the Watch App Store but the latest available version there is still 4.3... Could it be that it will take some time until it's showing up everywhere?
Too bad I was already running today and a thunderstorm is expected here in the next hour. Got to wait until tomorrow.
