For the past few hours, I've been having major issues with Siri. She's pretty much unresponsive, whether I'm trying to use the Dictation button in a text message or interact with her in general. I've disabled Siri, powered down the phone, then restarted Siri; she worked once and then stopped again. I also followed a tip online saying to put the phone on Airplane Mode, restart it, and then turn off Airplane. That didn't work either. Every so often, she'll respond, but more often she won't. Anyone else having Siri issues at the moment?
