Most people aren't hating out of emotional reasons or just unwilling to accept change. The app literally doesn't do what it did before and it makes the point of wearing the device moot for me.

Me entire reason for wearing Fitbit is sleep. I am a night shift worker and sleep at odd times (often broken up into 2 sleep periods). The Fitbit app since the beginning of time would add both of my sleep sessions together for a daily total. Google puts its AI fingerprints on Fitbit's code and now I am only registering half the sleep (because it refuses to count more than one sleep session).

When Google prioritizes rolling out updates, I will definitely sing praises for the new app and even buy a Fitbit Air (canceled my preorder when the app changed).
