Why is my MNGo stick blinking?

Hello, I'm encountering an issue with my MNGo stick and I'm hoping to get some clarity. The MNGo stick, which is a crucial component for managing my crypto wallet, has suddenly started blinking. Could you help me understand why this might be happening? Is it a sign of a low battery? Or could it be indicating a software issue or a need for an update? I've checked the user manual but haven't found a clear explanation for this blinking pattern. Could it be a security concern, and if so, what steps should I take to address it? Your guidance would be greatly appreciated.
