18.23 lost audio prompts

Since upgrading to 18.23 i seem to have lost all my audio prompts, no pace updates, lap updates, nothing on the phone BT. (i haven't tested direct watch bluetooth).

I've tried toggling the prompts on and off individually, ive tried rebooting the watch but nothing seems to help.

The watch still vibrates and shows the update on screen but i have no audio of anything.  Not lap count, pace, heart rate or anything else.

Any ideas?
