You’re fine. It’s a voluntary recall, they were pretty much forced to do one by the cpsc but the boards are working as intended. They’ve also released a firmware update that makes the board vibrate and make a noise as an additional safety measure. (Keep in mind this cannot be disabled under normal circumstances so if you already know how to ride safely you should consider if you want to install the new firmware or not)

Of course always wear at least a helmet and wristguards when riding.
