I am trying withdraw the rewards and it keeps saying, “Incorrect device detected. Expected device c0fa200…, but got device 8016011… Please plug in the correct device.” What does this mean and what am i supposed to do?
Sounds like you are using a Ledger or other hardware wallet and switched the hardware device, since you set up the wallet.
You can delete the wallet from the wallet app and import with the new device.
(If you did not switch devices, but have multiple of them, it’s also possible that you just mixed them up.)
