BLE scan works when connected to development pages but quits when app is downloaded to my phone

I am struggling with a BluetoothLE issue. The BLE process, scanning/connecting works fine while I am connected to the development environment, when i download the app to my Pixel2 with Android11 the scan process fails witout any errors- nothing shows up in my listview. I get a request for Location permission when first run and I grant it. Suggestions?

Frustration abated. Thanks much for your time.
