      Posted .

      Hi there, I’m sorry this has been your experience. Bluetooth issues are frustrating. Please reach out through support.ouraring.com and start with Finn. Finn can walk you through connection troubleshooting and, if the ring shows a hardware issue, help move the case to the next step. If you’ve already done that and still need help, send us a DM on Instagram or Facebook so our Social Care team can take another look.
