Actually something wrong with everything in Garmin connect. No sleep data, no steps. It shows steps in main page but then not on day or week view. No sleep data too.
I'm having the same problem. Sleep data is present on my 745 but won't sync to the iOS app. My Index S2 also got disconnected from the app this morning, so something is strange.
I'd consider it temporary - this is the first time it's happened to me (and my wife) in an absolute age. Yesterdays sleep took a while to sync so I assume it'll come over when the back end is fixed.
This is temporary Fabio. It's happened on my watch and my wife's as well. Things like this don't happen often but they do happen. I have been using Garmin now for 3 years and I have only had a couple of minor hiccups like this.
