Insta publishing fully broken

I've had problems with Express in the past, but I have been able to "Refresh Instagram Token" and got my posts working again. But this no longer works. Same Express publishing to the same IG account now fails with every scheduled post. I get the Token Refreshed message, but when I try to publish, it fails. (I also restarted the Chrome browser.) Refreshing the token doesn't work. Is this a know issue?
