Homepod Siri in Spanish(Spain)

Last summer I bought a Homepod during my holidays in USA, the device was not available in Spain yet.

I installed the homepod a home and speak to siri in English without problems.

With iOS 12.0 Spanish was made available, so I configured Spanish(Spain) language and I could interact with Siri without problems.

Now with iOS 12.1 is not working anymore, the strange thing is that if I configure the Homepod in Spanish(USA) it works, but I need to configure the device to Spanish(Spain) to have the same configuration of my iPhone and speak normally in Spanish.

Anybody else with the same problem?
