Unable to listen to WhatsApp messages using Siri on multiple iPhones

Since 4 days ago I´m not able to listen to my whatsapp messages using siri. I use this feature for my blind mom, but this issue started happening last saturday june 14th and the same happens on my iphone and my wife´s iphone, so it´s not related to any setting.

Original Title: I´m no longer able to listen to my whatsapp messages using siri. I have exactly the same situation in three different iphones so it´s not a configuration issue.
