edit sleep on IOS, does not update watch

Same beaviour in android App.

I've had a long standing support case with Garmin over this issue. It has been happening on & off for months. You just never know when it's going to stop/start working until you modify the times. By then it's too late. It'll usually stop working for a few days then start again. Although this time it hasn't worked for nearly a week.

You might also find that following modifying the sleep times you lose the movement data from the chart, even though when you look at GC on the web it is still there & the modified times are correct.

I appears to be a server/app sync issue rather than an issue with the watch itself. I do wish Garmin would fix it once and for all.. Try raising a support ticket with Garmin to add a few more voices to the issue

Same here. It did the «reversed» sync once, on the previous beta. The IOS GC app is full of bugs. My W/Kg under performance statistic has been the same for months due to the problem that the weight in that statistic never update. No matter what i choose, 4 weeks, 6 months or 12 months, the weight is the same. I weight with the index scale every morning.
