I have smart lock set to not require iris unlock while at home. It worked yesterday but I've been home for 5hrs now and it still wants to scan my iris or pin each tone. Location services are on.
I have mine set to my G3. When I go to bed at night, my phone stays on the opposite side of the house (breaking the bluetooth connection with my watch). When I use my phone in the morning, it requires that I unlock it (using iris scanner) just like it is supposed to. During the day (when it is within the range of my G3), it stays unlocked (according to plan).
