Please, note if you want to use two devices for one character.
In fact we transfer a character only when a player changes game platform because updates for different platforms cam be available not at the same time and a player can have problems with the game.
If you are ready for it send us your ID of two characters on different platforms at https://support.my.games/gh and point at one that you would like to save.
Pay attention to the fact that all characters should be connected to the same account in social media.
Where to find your ID-numbers you can see here
