I was excited to see that this would be fixed with 10.3, but I am still having this problem. I see the context locations, I’ve reset them, created new tasks with them, and still I get no notification. I can even see that I am in a location that I should get an alert at, while I’m there, and nothing.
Am I missing something? iPhone 6s, iOS 10.3.1 (14E304), current version of OmniFocus with Pro Upgrade. Location flags are set in privacy to allow communication, etc. Notifications are on, and work for timed events.
