To change the background on Insta Stories, start by launching the app. Once in the Stories section, search for the 'Background' or 'Theme' option. It might be hidden in a menu or accessible with a swipe or tap. From there, you can select from pre-installed backgrounds or upload your preferred one.
Well, first open your Insta Stories. Then look for the settings icon, usually represented by three dots or a gear. In there, you'll find the background settings and can choose from the available options or upload your own image.
You can do it by going to the settings within the Insta Stories feature. There should be an option for background customization.
