AirDrop icon missing on new MacBook Pro M4 with Sequoia

Hi,

I just got a new MBPro M4 with Sequoia

When I use my iPhone 13Pro to share a file via AirDrop, on my phone I only see a white empty icon of my MB (see image for reference)

It works, obviously, but I don't like it

Is there a way to get the icon image appear again?

My image profile on iCloud profile is correctly configured, and so is my image in my contact address book

Thank for any suggestion!
