Double click the home button. A bar with all your apps should pop up. Go to settings then to time and date. Change am to pm or pm to am then go back to your game. If this doesn't work , do the same thing but instead of the am pm , just switch the day ahead by 1 then go back to your game.
So this is a glitch I found while playing morphs you can get your morph to health recovery fast and you don't have to wait it is simply.
1. Change your device time to a few hours and this also works for the training thing.
2. If this doesn't work then it probably means that the glitch is already over and they must have fixed it.You can also make it work by any other game that includes waiting here are the listed games, dragonvale, monster galaxy, and any other waiting game.please like this.
