Breathwork and sleep tracking

It seems like this is a semi-regular problem, but: I have my sleep times automatically set; I will frequently do the Tranquility Breathwork activity (which ostensibly is supposed to be used to prepare for sleep), review and save the activity when it's finished, then turn my light out and go to sleep - which usually happens almost immediately. However, it's pretty consistent that if I do this, my sleep won't be detected for at least an hour if not more and I will see a "shorter than optimal sleep time" in the morning.

Has there been any movement on this or related problems?
