Sometimes, I hear ALEXA say something while I am watching television. I know that she has replied to the television, so instead of pausing the TV and asking her to repeat, I tell myself that I'll check the app on my Fire Tablet later to see what it was she said. But later, I'd check the App, and NOTHING was there. No question, no answer. I had planned to listen to what she "thought" was the question.
Sometimes she is giving me a reminder that I requested earlier, but I don't hear it either because the TV is on, or because I'm out of the room at the time. It would be very handy if the app would give us the option to display a list of everything that Alexa has recently said.
Or program her to only delete the response from memory if we respond appropriately, but otherwise, let us ask her to "repeat recent reminders." or have her repeat the reminder later, until such time as we reply, "Alexa Thank You."
