I'll add another datapoint, I have three Yale YRD240-ZW deadbolts, and am on R066, and the status on the connect.securify.com is almost always wrong -- unlocked, when they are in fact locked. Local web UI is more reliable (checking just now via VPN, it says all are locked, while connect still says all unlocked). iOS app previously was blank for these locks, now says affirmatively that it can't update sensor data.
