Auto reply while driving not sending a message

Hello,

My Iphone doesn't send a message when the DND while driving is activated. My contact doesn't receive my auto-reply text when they call me or when they write to me. I checked everything I could:

• Settings, Focus, Driving mode, Auto-reply to: all contacts
• While driving: activate manually (I activate it trough the Control Center)
• Settings, Focus, Share across devices: activated (I tried to disactivate it but it doesn't change anything)
• Settings, content & privacy Restrictions, driving focus -> is allowed
• Settings, Privacy & Security, Focus -> Messages is activeted
• Settings, Messages, Allows messages to acces -> Focus is ON
• I deleted the Driving mode in Focus and I created a new -> it doesn't change anything

I use iOS 16.4.1 (is up tu date). I've got 2 sim cards.

Thanks for your help!
