Re: PvZ 2 on mobile won't update progress

Firstly, I would like to ask whether you entered the code correctly. If it didn't work...

Secondly, I would suggest you clear your recent tabs and try again. If it still didn't work...

Thirdly, try uninstalling and reinstalling your game and try again. If it didn't work again...

Lastly, go to EA help: https://help.ea.com/en/contact-us/?product=plants-vs-zombies-2&category=game-information&issue=tips-and-tricks

Hope this helps!
