The official Japanees Pokemon website has updated with some new information regarding how Pokemon transfers will work from Pokemon GO to Pokemon HOME.
According to the support page, it seems that players may have to wait for a certain period of time between transfers from Pokemon GO to Pokemon HOME. It is further stated that players can use Pokecoins to reduce this waiting time if desired.
A rough translation of the page in question can be found below:
[Pokémon HOME] How much do you need the “Pokecoin” of “Pokémon GO” to transfer Pokemon from “Pokémon GO” to “Pokémon HOME”?
After transferring Pokemon from “Pokémon GO” to “Pokémon HOME”, it may take a certain amount of time to make the next transfer.
This time can also be shortened by using Pokecoin.
Please wait for future public relations for details on the transfer method.
Currently, it is unknown how long the cooldown will be, as well as how much Pokecoins will be needed in order to reduce it. We will be sure to report back with more details as they come.
