Hey all, I was just curious if this was a feature or something else. When I use Siri on my 6s Plus, I don't get an initial double tap/vibrate on initiating Siri. I only get it when Siri acknowledges a command and executes it. I could have sworn it worked on my 6s Plus before? I upgraded to 9.1 beta and did a restore but after some issues with my restore causing serious battery drain I wiped the device again and dropped to 9.01 However I'm running 9.1 on my 6 and 5s and I get the double vibrate tap on Siri execution. Anyone else experiencing this?
