I flew from London to New York last night, thereby moving 5 time zones. This seems to have caused confusion with the app, and loss of data.
My night's sleep after arrival does not show up inthe app - it still displays the previous night's sleep. Also today's stress graph etc are all from yesterday.
This is particularly annoying as when travelling like this, keeping track of sleep is particularly important.
I imagine that the app currently works in "local time" rather than saving everything in UTC and then displaying relative to local time? I'm sorry to say that Google Fit seems to have coped rather better!
Thanks for your help.
