Just purchased the device and downloaded the app. The device refuses to connect to the app on the phone. (Moto G7) tried uninstalling and reinstalling the app no difference! I contacted support a week ago with no replies back regarding the problem or a fix 🤬 Spending $80 for a device that was purchased for monitoring heart health and not having it work is very concerning. At 70+ years old I was hoping to be able to catch any early conditions prior to having a bad situation.
