I realized that my Shortcut was pausing to await manual input so I edited the Shortcut.
Below is the “Notes Test” shortcut I created in Shortcuts as well as the corresponding Notification I created in the Pushcut server.
I no longer get the Pushcut Server request for manual input. When the notification is activated all appears to work - the Pushcut server acknowledges a request and if I activate the notification by URL I get a Success message. Interestingly however, the Note is not created. Or rather, the Note is created on a delayed basis and only appears in my Notes a few minutes later - and after I have created an additional note manually using the arrow at the bottom right of the Shortcut screen. Yet running the shortcut manually consistently creates a note immediately,
So why would the shortcut create an Apple Note immediately when run manually but not work or work on a delayed basis when executing the shortcut via automation?
