Personal requests borked?

Hello, is anyone on iOS 15 and the latest public release HomePod software have personal requests working? All my HomePods are saying “I’m not sure what you mean.” Had hoped this was a beta thing but seems to be the case on the public release for me.

Would love to know if it’s working for others - if so I may try a full wipe of my phone as resetting my HomePods hasn’t helped.

I reset my HomePod and HomePod mini and it seemed to help.
