Audio prompts and OnePlus (11)

Hi

I have just gotten a Venu 3. 

I have a OnePlus 11. Android 14.

Both phone and watch are up to date with all apps and OS. 

Garmin Connect on phone should have be allowed to do everything. 

I have a pair of Jabra In Ear 4 headphones. 

They can connect to both phone and watch at the same time. 

I have read several stuff around the web about audio prompts, but I cannot the any what so ever in the head phones. 

I have set it up to give audio prompts on every lab. 

I have read something about the Oneplus being the issue. 

So - have anyone with any android phoge gotten it to work?

Has anyone with a OnePlus gotten it to work?

Regards 

Michael
