About 2 months ago, I used this article to set up a series of flows that triggered certain actions only when both my wife and I were away from home (Nest thermostat down, lights off, door locked, etc.): http://joeyzacherl.com/2017/06/sharing-location-through-variables/
Then, I used the same process to trigger flows when either of us (or both of us) arrived home.
Everything worked flawlessly for a couple of months, but a few days ago all of those variable-based location flows have suddenly stopped working, and I can't figure out why.
All of the relevant flows still show as active, and I haven't made any changes to our home automation setup. One day everything worked. Then the next day everything stopped working.
Any ideas? Did something change in the way Stringify handles location sharing through variables? I saw some location-related forum articles for Android devices, but we both have iPhones.
Thanks in advance for the help!
