[Publish] Why aren't my Instagram posts sending automatically?

Summary Checklist
Finding past Reminder posts


Unlike other social networks like Facebook and Twitter, Instagram only allow third party apps to publish posts automatically on behalf of users under specific conditions. Therefore, Buffer Publish offers two ways of posting to Instagram: Direct Scheduling and Reminders.

In order for Buffer Publish to send posts automatically, your Instagram account will need to be a Business Profile and you'll need to have Direct Scheduling enabled. Here's a step-by-step guide on how to get set up! Additionally, you'll need to be sending posts that meet the criteria for Direct Scheduling.

Taking a look at your scheduled posts in your Queue, any posts that are going to be sent to your mobile device as a Reminder will show a small bell icon and notice of when the Reminder will be sent to you. If you've never worked with Reminders, here's a great guide to get you started.


There can also be a couple of other factors that affect whether or not your post is sent out automatically, so we've created this checklist to help you identify any missing pieces and make sure you've got everything in place.


Do you have an Instagram Business account and are you set up with Direct Scheduling?

If you've set up Direct Scheduling successfully, you will no longer see an invitation to set up Direct Scheduling at the top of your Instagram Queue. If you do see this invitation (shown below), you'll want to follow the steps in this guide to get thing set up correctly.


Does your post contain only a single image or single video? A post with multiple images will be sent to your mobile device as a Reminder.


Does your image or video meet the aspect ratio and video length requirements? Instagram only allows us to send images and videos automatically if they meet the following size requirements.

Aspect ratio range Aspect ratio range as numerical values
Image Between 4:5 and 1.91:1 Between 0.8 and 1.91
Video Between 4:5 and 16:9
Between 0.8 and 1.78

All other posts will be sent to your mobile device as a Reminder. See our detailed sizing guide for more information.

When you are composing your post and you've added your video or image, we will alert you if the media is falling outside of the required aspect ratio or video length requirement. You'll see a bell icon and an alert message saying that the post will be scheduled as a Reminder post.


Do you have the "Set Instagram Reminder for all posts" setting turned on for your Instagram account? If this is turned on, all Instagram posts will be scheduled as Reminders. The screenshot below shows where to turn that setting off.


Did you have any posts scheduled before you set up Direct Scheduling? Any posts scheduled in your Queue before the switch will still be scheduled and sent out as Reminders. If you'd like them to go out automatically, and they meet the aspect/video size requirements, you can recreate the posts and reschedule them in the Queue.

Where will I find scheduled posts that didn't go out automatically?

If your post was scheduled as a Reminder post, you will find it in the Past Reminders tab. From here, you can send the post to your mobile device to finish it up in the Instagram app and post it manually. You can also share the post again from this tab.
