Instagram began testing a new option that will allow you to customize the display of publications in the profile, changing their order at your discretion.
The new “Edit Grid” option will appear in the profile settings and will allow you to change the order of posts on your profile, regardless of the date of publication.
This option will be useful if you want to highlight certain publications and draw extra attention to them.
This is a major upgrade that can cause a bit of chaos in profiles. So a more viable alternative is to pin multiple publications to the top of the page, as it works in Tik-Tok.
