Problem with AirDrop

Hi guys, I have troubles with seeing of my iPhone on Mac. I have already tried restart, switching from on to off and repeating this. I did all updates of system and it is still the same. Would you know to solve it? Thank you very much. Last words. Only I really can see is my Mac on iPhone. So my AirDrop works only from iPhone to Mac, not in opposite direction.

Thank you a lot.
