Mystery Gift

Probably a stupid question, but I started the game two weeks ago, received the Delta Feebas and the Book of Leaves Mystery Gifts from the main menu, but the delivery man hasn’t shown up at any of the Pokemon Center/Pokemarts I’ve been to thus far. Do I need to do something more then download the gifts onto the save?

He is at the back so have you checked everywhere?

I’ve been talking to everyone in the building in each town, nothing. I check the mystery gift menu again, and it said nothing new, so I didn’t make a new file or something (Since I would’ve had the book of leaves if I did).

I don’t rly need mine so u can have it if u want cos I am quite far into the game and rly couldn’t be bothered to lvl it up and already have multiple good ghost types
