Factory reset issues

Does anyone know what to do if the clip 5 does not factory reset? It's driving me crazy. Flashing beeping, working but nothing when doing the factory reset, no short beeps, nothing. Does not even connet to find hub, it tries then says cannot do it and I should check my Bluetooth and internet connections. Both are on. When trying to connect via Bluetooth (pb-xxx) it says I need an app, while the app is already installed. Did I get a faulty product?
