Breathing variation no data

Hi all,

I Was just looking at the breathing variation screen which was added as a sleep screen in the latest stable update a few days ago.

For what ever reason mine just has text telling me no breathing variation data is available and to sleep with my watch on and pulse ox enabled.

I meat both criteria the message states and have done since owning the watch (Pulse ox is set to all day not sleep only if that matters). I wouldn’t have imagined it requires a baseline/training period like skin temp or HRV.

Does anyone else have this data showing or does anyone who was on the beta know if there is x day training period?

Many thanks
