Water temperature not being recorded in the health app.

I was so pleased to find an entry called ‘Water temperature’ in the ‘Other data’ section within the Health App.

However, despite numerous cold water dips, nothing is recorded!

Please don’t link to the how to use the depth feature Apple section. I’ve seen it many times.

Yes, my Ultra measures depth and temperature automatically … I have seen it on the face when in the pool.

BUT it is not recording it.

Info in the health data says, ‘….it can be entered manually or recorded by a device that adds data to Health’. I have an Ultra watch.

Please help link the water temp to my Health app.
