I've had a problem with my device, that it didn't syncing my datas with the app. So I decided to reinstall it, but now it can't find my device on bluetooth while I trying to reinstall. It only shows "Select An Accessory", but nothing appears, nothing happens. Then I tried again a few more times, delete the app, disassociate my product, factory resetting, turn the bluetooth on and off, restart my phone, but nothing works. I can't install it, because of this issue. It's not my first problem with this product, it's so annoying.. Any idea what should I do now?
