How come the Ultra Beasts and Necrozma get boosted exp even though they were not traded?

Question

I have never traded them and they are my Pokemon but it says they get boosted exp.

Comments

When you max out affection in Poke Refresh the Pokemon get boosted EXP.

Nope they are not at max, in fact the highest is Necrozma at 3 hearts

You only need 2 hearts to get the Exp boost.

Well that explains it

Answer 1

It's only possible if these conditions apply:

• Check the OT of the Pokemon again, if it's not you, then the Pokemon was traded and receives boosted EXP.
• Does the Pokemon that was receiving boosted EXP. have two hearts or more in Pokemon Refresh?
• Is it holding a Lucky Egg?
