I do a 4.5 mile walk every morning and record my pace, calorie burn, and distance. I record my overall pace but also like to record which mile was my quickest and the pace of that mile. Starting a few days ago, though, my Fitbit Sense is not giving me the per mile breakdown. It only says Lap 1 with a pace/mile and distance - neither of which is accurate of my walk. What happened to the ‘per mile’ breakdown? This is also happening with my husband’s sense, so it’s not just mine.
You are not alone. I’m having same issue with my Charge 5. Like you, it just started a few days ago. (My old data also no longer has per mile pace.) I spent hours trying to figure out if it was something I did and looking for solution. All I‘ve found is your post. Wish I had more than empathy to contribute.
