To sync your account, make sure to link a recovery email first. This can be done by going to the game's Settings and selecting "Protect your account."

On your new device where you want to use the same account as you did on your original device, go to the game's Settings and select "Recover lost account."

This will send a code to your email. Once you receive the code, copy it and go to the game's Settings > Link Device > New Device and paste the code you received.
