Siri won’t listen to anyone’s voice except for mine.

As far as I can tell, this began with the newest update. For all things that use Siri, including dictation, activating Siri by voice, and just having it listened to any voice commands or questions. It is now ignoring both of my children, but it still listens to me just fine. This is worrisome in case my children need to use my phone in an emergency. I saw there was some sort of new restrictions for Siri or something online but anytime I click to get further details where it indicated it had nothing. Is this a new setting for what is the issue here I need my my children to be able to utilize serious features for various different reasons and it completely ignores them no matter how they say it. Is it may be some sort of child filter? I don’t know but I need to figure this out ASAP. Someone please help! Please do not respond with like the most obvious basic troubleshooting Siri suggestions because this is a very specific issue and I have looked through the settings provided in my settings app on my phone multiple times. Please know “turn it on and off again” type responses, please lol. Thank you very much! Hopefully someone can figure this out! It’d be great if Siri support could actually respond to this as well with a real solution pretty please and TIA.
