Intercom not working correctly

Hi, I have 4 homePodes in different rooms in my house. All of them are setup correctly and updated. Most of the times the we try to intercom an individual room or even the entire house using Siri, it doesn't give us the "pause" to recorde the message and send it straight away. For exemple, it should be: when I say "Hey Siri, Intercom Living Room...PAUSE TO RECORD MY MESSAGE... and the them Siri makes a sound and send it. Some times it works properly but some times it does not give that pause to record the message.

Anyone having the same issue?
