GoKawiilOura acknowledges Ring 4 sync bug tied to firmware 2.13.1
Oura has confirmed that its firmware version 2.13.1 update is causing some Ring 4 devices to stop syncing with the companion app. The company says the issue arises when users switched phones after initial ring setup without performing a factory reset, and typically blocks syncing for a day or two. Oura notes that placing the ring on its charger and opening the app resolves the problem.
