However, not everyone who downloads the newest version of the app will receive this feature as it is still being rolled out in stages. Additionally, Instagram has not made any official statement yet. In case you did receive the update, then you should see an “Add Account” option under the “Clear Search History” option on the settings list. This basically means that you can now add or create another account to use simultaneously with your present account already logged in.
As of now, iOS doesn’t seem to have this feature even if they also have the same Instagram 7.12.0 version. If you want to check whether you have this feature, click here to update; and don’t forget to let us know about it.
