I will talk briefly about Instagram. How to restore deleted posts on Instagram. Before I begin, let me it clear that this post is a medium so that you can get any lost or deleted posts.
You have to go to the account through the setting. Then go to the deleted option and go there and click on the menu.
Here, you will find the option to delete all posts, stories, and videos. For example, if you want to get back the deleted Instagram post, you have to click on the three dots at the top right.
You have to download Instagram again here. You need to prove your identity using mobile number otp. You can then return the deleted post to your Instagram profile page.
