After trying to play with the different Sandbox entitlements I got to the point that while the app is open I can see it trying to connect to iCloud (running tcpdump), but somehow it doesn't refresh the list with the latest info. It does work perfectly when I run it via Xcode, but as I sign and deploy the app (production) it doesn't any more. Any one has any ideas? Yes, Incoming Connections and Outgoing Connections are ticked.

More info, if I disable App Sandbox on the entitlements then it works like a charm. I tried Adding Outgoing Network Connection to the entitlements and re-enabling the App Sandbox, but again it doesn't work... What am I missing????

Yeah, just tried it. It prevents from the quick action from being called when needed (if the app in the background).

I do see a problem tho... if the user does indeed want a quick action, when the app is in the background, he clicks on the quick action but the if !alreadyTriggered will prevent it from getting triggered....

Thank you. I don't think this was an intended action. This is a nice workaround, however, I'm trying to understand if there is a way to "empty the cache" or set the quick action to nil so it doesn't trigger again.... Let me try this one in the meantime as a workaround.
