On the activities that have synchronized today from my Forerunner 15, referred from last 3 days, no elevation data are displayed on Garmin Connect and also the "Elev correction" option is no longer visible.
Up to the last Thursday all the activities I had recorded with the same devices presented both elevation data and "Elev correction" option (setted to on). The software in the device is the same (2.50.0.0), no up-dates.
Please restore as soon as possible! :-)
