If you don’t see your Instagram profile picture in Later, here are some common reasons why:

• You haven’t enabled your Instagram business or creator profile features. If you have an Instagram business or creator profile, your profile picture will only show up until after you’ve granted Later necessary permissions through your Facebook.

• You have an Instagram personal profile. Due to limitations from Instagram, we can’t pull in the profile picture for Instagram personal profiles. You’ll see a gray avatar instead.
• There’s a delay. If you’ve enabled Auto Publish and still don’t see your profile picture, there may be a delay. Give it some time and it should show up.

Note: We’ll pull in your profile picture when Instagram allows. At this time, you can’t upload your own profile picture to Later.
