Old feed shown on page. Up-to-date in admin panel

It seems that my instagram feed is not correctly updated. The feed only shows the state of the last refresh when I was in the admin panel of the plugin and actually clicked on the feed and saved it again.

The feed in the admin panel shows the latest posts, but the ones in the frontend stay the same.

Other than that the instagram profile is a business account, it shows that the shortcode is used at 1 page and the plugin displays no errors whatsoever.

It used to work correctly in the past without any issues.
