Recent disappointment,, I've been using MapMyRun for alittle over a year seamlessly until recently, when I updated from the Galaxy Active 2 to the Galaxy Watch 4. Now I nolonger get anything on my watch, even when I'm moving. I click start activity and it does absolutely nothing. I specifically use MapMyRun in conjunction with my HOVR shoes (avid runner) to track my speed, cadence etc. while training. Super sad, hope they update this feature!
