When you wonder why the automation isn't turning off Work focus after you've been home a while, and realize it's using the wrong device's location to geo-fence.
Then add another automation for the same location on another device.
Then can't delete either of these, because your phone and tablet both still show two entries with details from the original automation entry because deleting the automation doesn't do nadda, and your watch doesn't show any automations.
Then you finally say screw it and delete the entire focus.
That's debugged. o(*_*)o
