A Shortcuts automation with the "When I get a notification" trigger does not run for every delivered notification. There is no error or indication that a run was skipped.
Repro (iPhone 16 Pro, iOS 27.0.1 (24A446)) :
- Create a shortcut with the "When I get a notification" trigger for Instagram and turn on its automation.
- Add a single "Append to Note" action that appends the notification's Title, Body, and Date.
- From another device, send 10 numbered DMs within about 15 seconds.
Result
all 10 notifications appeared in Notification Center, but only 7 entries were appended to the note (#2, #4, #6 missing).
My app relies on this trigger to save notification history, and users report missing notifications. Is this trigger expected to run for every delivered notification, or is it best-effort? If anyone else sees this, filing a duplicate referencing FB25255777 would help.
