Can I connect my Instagram account?

Unfortunately, Instagram's terms & conditions do not allow most apps to post directly to them. As a result, we won't be able to integrate with them unless they change their policies.

However, we do have an integration with Buffer and they've created a workaround to post on Instagram where you can schedule reminders (here's how it works ).
So if you're looking to post your Snappa images directly to Instagram, the easiest way would be to sign up for a free Buffer account (they also have premium plans) and then you can easily add all your Snappa images to your Instagram queue in Buffer.
