I'm not sure if this is part of the update as it seems to be a recent issue, but I have days and days of worth of activities completely missing on the app. I'll have tracked on my watch either run, boxing or spinning each of the days and there is nothing showing. I'm missing about 3 weeks of data for the last 2 months.
I too am getting the "would you like to end this activity" message mid workout, then if you don't catch it, it switches you off!! Seriously annoying!!!!
