When I schedule an Instagram Reel, will it automatically post for me?

This a great question!

So, Instagram does not currently allow third-party platforms (like Plann) to display previously posted Reels, Reels analytics, or allow Reels to auto post. You'll want to use your Reels space inside Plann to design a strategy, store and schedule video files, save hashtags, Reel-y great ideas and execute at the right time. We’re furiously watching out for their updates and as soon as they open this feature to us, you’ll have it!
