BLE Extension (20190701 or 20200616)

I am trying to utilize the ScanForService in either of these BLE extensions. My understanding is that you simply replace StartScanning with ScanForService (with the service UUID). When I do this my list picker shows nothing. This was a new project not one that was converted from an older BLE extension. Are there any examples using this new extension in this manner?


I believe the discussion in the below link, would or may provide some important information regarding your concern.
