seeing the Bluetooth...but failed connection

The problem got bar is really cool, but like Reagan’s review I too am have connection failed issues now. It’s not hardware, because both of my light bars serial numbers show up when searching for Bluetooth devices. However there is a connection failure. How to fix this please. I’ve uninstalled downloaded and reinstalled the software but still not able to control with the app, despite the app seeing the Bluetooth.?...thanks
