Siri can't set a timer for me (or set an alarm clock). He/she just replies "working on it" and then "something went wrong". This was working earlier but not anymore. Siri can still tell me what the weather is or else. However timer is the one thing I use Siri for the most (only I would say). When I'm cooking I don't want to (or can) touch the phone I like to speak to it. I really miss it.
