I have This problem occurring.
I bought them just a couple of days ago.
Latest iPhone Galaxy Buds app
The option is selected to enable the mode during calls but it just greys out during a call and I cannot hear my own voice.
I was really looking toward to this functionality.
Thanks for the suggestion but there is no connection problem.
I’m using the latest app. I’ve tried resetting the buds. Still no ambient during calls. Maybe I have a faulty set.
