You can edit the description and price of your listing. When you do, it will once again go through the approval process.
Here's how to do it, Go to ‘My Stuff’ and open the item you want to edit.
For iOs, the 'Edit' button is at the top right hand corner.
For Android, tap on the 'More'' button at the top right hand corner and you'll find the 'Edit' button there.
