Recently started using the HIIT exercise function starting it from my Charge 6 with Move 30 seconds and Rest 10 seconds interval. Once I manually sync with the app, the data reverses to show Move 10 seconds and Rest 30 seconds.
Of the threads I could find, it seems this issue was first reported back in 2018, 2019 and more recently 2023.
Is anyone using the HIIT function experiencing this issue?

Hi @KatherineNY
I don't use the HIIT workout so I don't know if this is a new issue.
For now, please submit this bug using the Feedback feature in the Fitbit app:
The feedback reports go to the team for review.

@RiekoC Thank you. I have but I'm not holding my breath on the fix. Maybe the interval/HIIT workout option isn't very frequently used so it gets no love from tech support given that it's reported years ago.
