Audio lap alerts disappeared

A while back this Autumn, my Garmin 6s Pro no longer gives me audible lap alerts to my phone.

I get smart notifications from my phone to my watch, so it's definitely connected.

I've checked that Do not disturb is off; I've checked the auto lap settings; I've checked the lap alert settings.

I've also removed my device and re-added it. Turned the watch off and on again, reset the app....

It seems to have been occurring since a recent Garmin Connect update, or perhaps the IOS 16 update...?

I feel like I've tried everything and I just want my auto lap alerts to talk to me again rather than just checking the watch screen!!!!
