Instagram is testing a new feature that willlet users pin posts to their profiles.
Currently, we can pin(Highlight) Stories to the profile.
However, a user can maximum pin three posts at the top of the profile grid.

At present, the feature is in the testing phase and is available for limited users.
The other photo shows the three pinned posts at the top of the grid.
The feature on Instagram has been in work for months now.

The ability to pin a post can be helpful for users who want to highlight their favorite posts.
This feature will help those who post regularly, for example, content creators.
As their favorite posts are buried somewhere down in the photo grid.

This new feature will make the process easier and more straightforward.
A reverse engineer Alessandro Paluzzi has earlier shared a glimpse of the feature in January.
Instagram is not only testing the pin posts feature.
The social media giant is also the Recent tab option in the hashtags section.
The content is now seen under the top and reels tab.
