This seems to happen once every couple of months. Location modes stop triggering automations, specifically Webcore ones for me. Then within a couple of days it spontaneously resolves. I moved away from using the location modes to virtual/simulated switches as a result. Just one of the many Smartthings deficiencies I’ve come to work around.
Just adding to the #METOO movement… Would love to see a more reliable work around described…
Thanks!
