is it running better on on the new OS 3 update ? I had a lot of issues with my first one when I bought it in December. The step tracking was always off my a few thousand steps a day, took awhile to update and I hated that I couldn't watch the step count increase in real time. I sold it and went back to my old Fitbit flex. I called Apple support and was told there was no way to manually input your stride length. That I would just have to do gps connected walks outside. ( well during Chicago winters....that stinks) So I'm curious if any of these things have changed with the new update to the original watches ? Thanks !!!
