1. What device are you using?
2. If you're using an iOS device, are you using the native Calendar app or a 3rd-party calendar app?
3. Have you tried rebooting your device?
4. If you're viewing week view in landscape mode, can you rotate the device to portrait mode and then select the icon depicting 3 lines to enter list view?
