From the post on the 13.19 update:
Software version 13.19 for the vivoactive 5 is currently at 100% Release. You can manually download this software update by following the path below:
Menu > Settings > System > Software Update
Changes made from 13.17 to 13.19
- Improvements to Voice Assistant interactions with various Android phones.
- Fixes an issue where messages wouldn't dismiss after a timer with repeat ends.
I'm so confused. This is not an option on mine. Just a quick Google of "Does Vivoactive 5 have voice assistant" returns this:
Yes, the Garmin Vivoactive 5 does have voice assistant functionality. You can use it to communicate with your paired smartphone's voice assistant like Siri, Google Assistant, or Bixby. This allows you to start phone calls, send and respond to text messages, ask questions, and control compatible smart home devices. The main change with software version 13.19, which is being rolled out to Venu 3, Venu 3s, and Vivoactive 5, is improvements to the voice assistant function for Android smartphone users.
I don't think this options exists, or if it does, I am unable to find it. Which is it?
