It sometimes happens that Instagram deactivates your account for no apparent reason. In most cases, Instagram simply wants to know that your account is owned by a real person.
Fortunately, it’s pretty easy to get your account back.
Trying logging into your Instagram on your phone as you normally would.
Follow the on-screen instructions to “Learn More”.
Click on “Let us Know”.
Fill out the application to let Instagram know that there has been a mistake.
After hitting “Send”, your part is done.
In most cases, you can expect to get your account back in less than day.
