Writing Tool issue when using Apple Intelligence on iPhone 15 Pro running iOS 18.4

Ciao guys, on my iPhone 15 pro, recently updated to iOS 18.4 that extends AI also to Italian devices, I havn’t the writing shortcut on my keyboard. I mean i have writing tool that works fine, but I can only reach it tapping the text box to open the menu and suddenly tap “writing tool”. It seems a bug but I wanna check if I’m wrong
