Siri won't start shortcuts and replies "Sorry, I don't understand"

Siri can be fussy. Try renaming your shortcuts so their names do not “conflict” with other things Siri could recognize. Otherwise, in English, you could try “Hey Siri, run shortcut xxx” (désolé, je ne sais pas quel pourrait être l’équivalent en français).

Since iOS 18 it seems that Siri has been focused on place names or people’s names. I saw a few threads mentioning that Siri now calls the wrong person when it used to do it just fine.

I renamed one of my shortcuts to “bibibobo” and it ran fine from the Home Screen by just saying “bibibobo”. I wonder now if this issue on your end isn’t with the Lock Screen.

Hello lamaZZe,

Try to just say the name of the shortcut, i.e. “Hey Siri, xxx”.
