Garmin or Polar says it’s already connected to another YuMuuv account
A Garmin or Polar account can be linked to only one YuMuuv account, so you probably have a second YuMuuv account, often from a previous employer or another email address.
- Contact support from the email you want to keep, and say which other account can go.
- Support deletes the other account. Results from earlier challenges on that account are lost. Your current account and challenge stay as they are.
- In YuMuuv: profile circle (top right) → Your details → Change integration, choose Garmin or Polar, sign in and allow data sharing.
- Tap Update your data.
If the message still appears, open Garmin Connect, go to Settings → Connected Apps, remove YuMuuv and try again.
