When any gadget doesn't act as it should, the first thing to try is to turn it off and turn it back on; as you likely have done with a computer a few times. Alexa devices are computers, too. So, turn off Echo by removing the power to it, wait five minutes to be sure all gremlins have left the building, then power it up again. If it works OK now, you fixed it. If not, there may be an incompatibility with the app or program so close it and reopen it. I doubt there is a problem with the Echo since it appears to work, otherwise. If still not working right, let us know.
