Incorrect working out of the Height sensor
FR955.
I noticed that the height sensor does not work correctly! And in all training and at different locations.
For example, I am attaching screenshots from yesterday's race 21,1 km. 1 - FR 955, 2 - Fenix 6, 3 - Polar M2. We see that the Fenix 6 and Polar M2 have the same graphs, although the FR 955 has completely different indicators and graph!
What to do? How to be?
