Add images from Lightroom to Instagram

Hi there, 

Which version of Lightroom are you using? If you're using Lightroom Classic, I'd suggest that use the LrInstagram plugin to share images. See https://www.lrinstagram.com/

If you're working with Lightroom mobile, please checkout this article https://helpx.adobe.com/in/lightroom-cc/how-to/photo-editing-instagram-lightroom-mobile.html

Thanks,
