I am also very disappointed with this issue.
I have a galaxy watch active 2, paired with an iPhone. And one of the main reasons why I got the watch in the first place was to have a reliable and useful way to count my calories burned and calorie intake. But now I can only see how many calories I am burning during the day. I can not see the number of calories burned any previous day.
Are you going to add this feature? or I'd better return the watch and buy an apple watch?
