I've been bit by adding timers via Siri so many times because I use the timer as a sleep timer for youtube music. So the next day I go to set a timer with siri and its set to "stop playing" which makes no sound and therefore the timer is next to useless. :( So now I just set timers manually but it nullifies Siri.
