Ascent Data does not match Ascent from connect


I’ve copied the subject from a 5 years old thread that was locked but till today the problem remains …

When looking one activity of mine from yesterday I get 378m from GC and 377m from the watch which is fine but when looking the same activity on GE iOS I get 464m !!!! 

It’a a huge difference!

I’m on a 15 days cycling vacation I realized that I‘ve made bad decisions on courses based on wrong ascent provided by GE !

Come on Garmin. This is serious.
