There are several reasons why a game may crash, freeze, or have other technical issues. If you've been playing for more than one hour consecutively, then there is a greater chance of this happening.
First, try these tips to improve the performance of your game:
Close all applications.
When you exit an app, the app does not close automatically. For some issues, including game crashes, it is a good idea to close all applications running in background to free up your device’s resources.
If you're still having trouble, try restarting your device.
Restarting your device can help clear up more available memory.
Please ensure that your software is up to date and that your device meets the minimum requirements shared here.
If none of the above help, please contact us with as much information as you have regarding your situation.
