Made a pleasant discovery today. Last night I updated to iOS 13.4. I have two garage door openers from Insignia. Since the feature was introduced, my wife’s door always showed up in the CarPlay dashboard for Siri suggestions. I usually close mine in the Home app or ask Siri after pulling out the garage. Well just an hour ago, when leaving for work, I switched to the dashboard view in CarPlay to see if Waze would show up as one of the new features and low and behold, my garage door showed up in Siri suggestions. Hope this wasn’t a glitch and Siri can now discern which door is mine and which is my wife’s. Didn’t make any changes other than updating to 13.4.
