User with same permission don’t see inbound message

Hello,

I have a problem with flamingo and I can’t find how to solve it.
I use flamingo with contact 7 which works perfectly fine, all messages are stored.
But I checked with another user who has admin rights too and he can’t see the message that I see.
I looked at the right, we have exactely the same.

There is the meta data “post_author_email” which is completed with my email address. Is this a possibility that only me can see the message with my “post_author_email” ?

Thanks you in advance for your help.

Have a nice day.
