Quick Solutions
Still having issues? This is usually the deeper cause below.
If pairing fails after multiple attempts, the device may still be registered to a previous account — factory-reset it before trying to add it to a new one.
Keep the controller near the center of the layout for the best sync.
Pairing failures almost always come down to distance during the initial handshake — manufacturers seriously understate how close you actually need to be.
