There is mention of quick replies in oficial user manual here:
However I can not reply using Vivomove Style or edit replies in Garmin app.
I found out, this feature is only for (maybe specific) Android phones. I am using Xiaomi Redmi Note 9 pro (Android 10), but no other conditions were specified. For me this is essential feature. I also read similar posts on this forum, some users mention they can reply atleast 'yes'. What is official stutus of quick replies?
