There are a few ways to remove tag from Instagram. The first way is to use the Instagram app’s “Tag Manager.” To do this, open the app and click on the three lines in the top left corner of the main screen. On the left side of the Tag Manager, you will see a list of all your posts. Click on one of your posts and it will open up a new window with all of its associated tags. To remove tag from that post, simply select “Remove Tag” from the list and then click on it.
