This app really doesnt do anything if you only have a single JBL speaker. The only thing it will do is update the firmware on your speaker. This ha dinky happened once on my Charge 3. They really need to bring it up to feature parity with the UE Boom app. My biggest request is that they give the option to turn the speaker on from the app. The Charge 3 is a better speaker than the UE Boom and the UE Megaboom, but this app is far behind.
