I searched explicitly for an app that has a sleep timer. It has one, but it defaults to UNlimited! It needs to have a “set as default “ choice in the sleep timer so it can set to some number of minutes. But otherwise why not have it default to 15 minutes or a half hour? I don’t want it talking to me AKL night and waking me up again. Just for a bit of tine and then I’m asleep and want it quiet.
