Been having various issues with my Bolt for the last few months - seems like the company keeps rolling out software updates that fail to fix existing problems or create new ones. Among the ones I've been dealing with:

1) Sensor dropouts - Bolt starts displaying zero speed/cadence/and-or HR
2) Long time to recognize sensors - turn it on but takes 2+ minutes to recognize Tickr and speed/cadence
3) Syncing to Strava and other apps a mess - has to be retried every time
4) Live tracking stops mid-ride (though this seems to have gotten better).

Others have similar experiences? Seems like some pretty basic stuff that used to work well, and now it's not. Causes just a bit of concern . . .
