So Siri and VoiceOver have stopped working all of a sudden... I press down the home button and Siri asks "how can I help," Ive asked Siri multiple questions and it continues to respond back with an error of not understanding what im saying?! I've also tapped on the microphone on the keyboard and spoken clearly into the phone and the 3 pink dots appear then disappear like it didn't register anything I had just said... I've tried to reboot but isse persists... It was working fine before so not sure what could have happened. Any ideas?!
