Sleep data not showing deep sleep or sleep score

[Pip82]

Sleep data sometimes shows sleep score and deep, rem, light and awake times. Sometimes it only shows asleep, restless and awake and no score. Why is it so inconsistent?

From what I can tell, the inconsistency is due to poor product performance, that can only be resolved with a device FW and/or app SW update.  

My Inspire 3 always returns the detailed sleep charts (deep, rem, light), every day  My wife only gets the useless sleep bar charts that you mentioned, using 3 different devices (including mine), which happens when  Google is unable to determine what your sleep stages are.

Still no word of any kind from Google regarding when this sleep tracking performance issue will be resolved.

Hmm that's a shame. Thanks for your reply, at least I know it's not just me
