A. 1. Restart your iPhone: Sometimes, a simple restart can resolve app crashes. Press and hold the power button until you see the 'slide to power off' option. Slide it, wait for your phone to turn off, then turn it back on.
B. 2. Update the app: Go to the App Store, tap on your profile icon at the top right, scroll down to see if ZEPETO has an update available. If it does, tap 'Update' to install the latest version, which may fix bugs causing crashes.
