After the update Siri doesn't respond when iPhone is locked

Siri does not respond when locked

there was a time when i misplace my phone and i will call for siri and ask to play a song, and it does, and helps me find my phone way too easily, but i updated and now my phone will be on my face but wont respond to hey siri or siri,

ik it sounds dramatic but its true
