After the last 2 updates I briefly saw a new feature regarding breathing variations in the sleep section. However, in addition to newly questionable measurements in sleep and stress data since the updates, I am sporadically getting the message, "No breathing variations data.". WTF? Sometimes it's there and sometimes it's not??? I am ready to jump ship and go with Samsung. The last couple of updates and I no longer trust anything other than the time coming from my Venu3.
