If your band connected yesterday but won't reconnect today even though it's charged and Bluetooth is on, work through these checks:
- Update the app to version 6.9.1 or later - it makes band sync and reconnect more reliable, especially on Android.
- Confirm you are signed in with the same account email the band was originally paired to — connection errors are frequently caused by signing in from a different email/account.
- Make sure Battery Saver is off (it can block the Bluetooth/location services the app needs).
- Toggle Bluetooth off and on, confirm the band is charged, and reopen the Rolla app to let it reconnect.
If it still won't connect, contact support with the email address(es) you use so we can confirm which account holds the band.
Don't create a new account to fix it. Your history stays with your original account and the band stays linked to it, so a new account shows "Band already in use". If you already made a second account: in the account the band is on now, tap the band icon (top right) > three dots > Unpair band, then log back in to your original account and pair the band there. Data can't be moved between accounts.
Leave a hard reset for last. It deletes data on the band that hasn't synced yet.
Reconnect banner on Home: tap the X to hide it for 15 minutes. It comes back after that, or when you reopen the app, if the band is still disconnected.
