Broadcast Audio Source application not recognised by Samsung Galaxy Tab S11 and Buds3 Pro

I have programmed an nRF5340 DK with the Auracast Broadcast Audio Source application. I have a pair of Samsung Galaxy Buds3 Pro paired with a Samsung Galaxy Tab S11 running Android 16 and One UI version 8.0.

When I select Listen to Auracast Broadcasts on the S11, it says 'No broadcasts found'.

What else needs to be done please?
