Placing multiple animated items in a single Scene may cause the app to run slowly, or force it to shut down.
Solutions
- Close other apps that are running

1. Press the Home button at the bottom-center of your device twice in quick succession.
2. A list of all the apps that are currently running will be displayed.
3. Touch the screen of the app(s) you wish to close while swiping upwards.
The exact procedure will differ depending on the model and OS version of your device. Please contact your device's manufacturer if you have any further questions.
