Can you tag someone in an Instagram Story using a countdown sticker?

 Instagram doesn't provide a direct way to tag someone in a countdown sticker. The countdown sticker is primarily designed for setting a countdown timer for upcoming events or occasions, and it doesn't have a feature to tag specific users directly within the sticker.

However, you can mention or tag someone in the text portion of your Story above or below the countdown sticker, inviting them to participate or reminding them about the event you're counting down to. This is a workaround if you want to involve specific users in your countdown.

Keep in mind that Instagram's features and functionalities may change over time, so it's always a good idea to check for any updates or changes in the app's functionality.
