Worked for a few months. I had Google Fit synced with my Fossil Watch to sync steps and other health and fitness info. After some time, Fit just stopped functioning. Very slow to start up, displays incorrect data, would time out when trying to sync with Fossil, start or stop active tracking. I hoped that a hard reset of all of the data and cache would fix the issues, but upon trying to resync my Google account, I'm encountering the same slowdown and time out issues. It's literally unusable.
