I bought an Edge 130 in June 2019, used it for a few months and then the elevation page (graph) stopped working even though elevation gets recorded. Garmin replaced the unit two months ago, and now I am back to having the same issue even though it worked fine for the first few weeks. I was told to clean the barometric pressure sensors on the back (two small holes) but this did not do anything, and they never even go dirty in the first place.
Looking to upgrade to some sort of Wahoo if this does not get fixed. Clearly, it's been a known issue on this forum for a couple of years.
