Thanks for reporting this, there must be an unexpected edge case happening here that we'd love to track down.

One thing to confirm with you: have you confirmed that your sleep and workout data sources are prioritized the same way on Sonar as they are in Apple Health?

To adjust your prioritization, go to the Synced tab on Sonar, tap on Apple Health > Customize > Sleep / Workout data sources.

If that doesn't resolve the issue, would you mind sending some logs for our team to investigate? To do this, just navigate to the Profile tab, scroll down to the bottom, and tap 3x quickly on "Version." This will reveal a "send logs" button.

And do you mind clarifying what sort of issue you're seeing? For example, is there a certain metric like "steps" or "distance" that has the wrong data, or there's no data whatsoever?

Thanks for your help!
