Hey @dixynox,
Thank you for the kind words, we really appreciate your review here! It does sound like your account connection has become invalid. This means that the feed will keep working on the front end thanks to our caching system, but will not be able to get further updates. Try reconnecting your account on the plugin settings page which should fix the problem for you. Just click the button labeled “Connect an Instagram account” and select the “Personal” option and go through the connection process again.
If you would like details on why this happened or need further support, please start a topic in the support forum here, or reach out to us via the support form on our website.
Many thanks.
