Coming from a Garmin forerunner 645, I now have a Vivoactive 5. The screen is great but I am missing an essential feature and that is simply 'resume later'.
I do long walks and sometimes take a break. I then like to pause my hike and hit 'resume later'. It saves battery, but most important because of the very sensitive touch screen I had already several times that by accident the save button was activate, also by e.g. my jacket. This is horrible and for me really a reason to send it back. Unacceptable that a really basic feature as resume later is missing. I guess more people are pausing during exercise, to stretch, to do some groceries etc.
