I recently upgraded from a vivoactive 5 to the Fenix 8. I use the strength activity heavily. Although I'm thrilled with most of the overall upgrades, the change from an input number pad to a Slider for reps/weights inside of the strength activity is a significant downgrade in user experience.
I hope there is plans to go back to the num pad input method or at least provide the option within the activity to use one or the other. The Slider takes twice as long to edit.
Hoping Garmin sees this and considers it for future updates.
