I have a Foreo Bear, and I've been using it quite happily with the App, but have seen you can also just start it and use it by itself. I can turn it on, illuminate the little curve of lights that indicate the microcurrent intensity levels, but I cannot get it to start vibrating. What do I do next? I have tried double pushing the on/off button, holding it down for a longer period - nothing seems to work.
Help!
