Re: Pvz2 account link help
Firstly, screenshot your player id number.
If you have signed up to EA's email registration scheme, you can EAsily and quickly get a unique code to restore your gamedata to another device.
(Watch out for autofil leaving a blank space after your email address).
Bear in mind that your new install will treat you as a new player and your store offers will be different for a couple of days.
Once your new copy of pvz2 is up and running, screenshot the player id number again because every device now has a unique device id number as well as your player id number, which remains the same across all your devices.
You should be able to play pvz2 on both devices and google playstore updates your gamedata regularly (i think it updates/downloads every time that you visit the screen with your profile names).
Keep both of those screenshots safe somewhere, i suggest emailing them to yourself.
