After you re-authenticate your Instagram, your account will be linked to your UNUM profile, but you’ll now have to add it to your grid space.
Go to your grid space and tap the “...” on the top right of your screen.
That will take you to the grid space settings. Scroll down to “view with social account.”
Tap the “view with social account” button. That will take you to a page where you can select any of the Instagram account(s) you have connected to your UNUM account!
