Hi, would you help me with a similar issue? The Instagram feed was working fine until recently (probably the 4.5 update), but now it only displays a spinning wheel. I tried resetting my access token and disabling other plugins, making sure that the JavaScript wp footer function is there, and toggling Ajax just in case. My JavaScript console is clean in Firefox but has some errors in Chrome.
I was using the simple [instagram-feed] shortcode. Thank you!
Edit: The plugin is being used down here: https://brianhutsonmusic.com/#section6
