I followed this older post https://forums.garmin.com/forum/into-sports/garmin-connect-mobile-application/garmin-connect-mobile-android/1308897-get-audio-prompts-of-last-km-pace-every-km#post1308897 that discussed getting audio prompts on lap alerts. It says there is an audio prompts option under device settings in GCM, but I don't see any such option.
I am using vivoactive 3 music.
Is this supported ?
