Edg 500 probs

Guys since i have updated the software to new 2.30 version my edge 500 gone mad. It shows wrong speeds (by around 2kph), it stops measuring distance and then powers off although speed continues to change…

not to mention speed tracking is much worse - ie it moves widely from 33 to 39 whereas i am sure correct one should be around 37.

and yes I am referring to the same route i do every week

anyone experience the same issues?
