Sure, you can often zoom in on a story depending on the platform or software you're using. Some reading apps or websites have zoom features for better readability.
It might be that your device settings or the settings within the app or website where you're accessing the story aren't configured properly to allow zooming. Check those settings to see if there's an option to enable zoom.
Perhaps your device's settings are interfering. Make sure your zoom settings for the specific app or your device in general are enabled and configured correctly.
