Question about messaging

Hello
When I log in, a small pop-up appears telling me that I have a private message (from Rayhana), but when I go to my inbox, I can't find anything.
Could you please explain
Thank you
Have a good day

Hello Tom,

As far as I'm concerned, everything is working just fine!
In short, the test was successful.
Well done, and see you soon.

Hello Tom
Which test?
If you sent a message as a test, I didn't receive anything.
Have a good day

No, I just put TEST in the forum :()

I'm having trouble understanding. I apologize
Have a good evening
