Earning your purchase rewards
If you purchased an on-going subscription from the Shop or Offers, it will only apply each time you login to the game.
Subscription rewards are only given out when you log into the game, and have no timer on them (other than expiry date of mail sent).
This means that if you are unable to play the game or miss playing for the day, the subscription will continue from the next rewards or day listed. This means that you'll need to login each day to receive your rewards - you can't leave the game and login five days later to collect them all at once.
E.g: If I collect the rewards from Day 9 of my subscription but can't play for a few days, when I log into the game later I will receive the rewards from Day 10 of my subscription, but I don't receive Day 11.
