Since last week, my Garmin Edge has been responding slowly. This is mainly noticeable when displaying my power output while cycling. When I'm cycling and do a sprint, it takes about 3 - 4 seconds before I see my high wattages. The same applies when I suddenly stop pedaling; it takes at least five seconds before the wattages display zero. Previously, this was immediate. I have checked it with multiple power meters. Does anyone know how I can solve this problem?
