Can you tag someone in an Instagram Story using a third-party app?

Instagram does not support tagging users in Stories using third-party apps. Instagram's tagging functionality is built into the app itself and does not extend to third-party applications.

However, third-party apps may offer other features and functionalities for creating and editing Instagram Stories, such as adding effects, filters, or templates. These apps may enhance the storytelling experience but may not include the ability to tag users directly within the Stories.

Keep in mind that Instagram's features and policies may change over time, so it's a good idea to check for any updates or changes in the app's functionality or the policies related to third-party apps.
