Simple, but it works

I had been using a different add-on the whole time until it just stopped displaying anything. That’s why I fiddled with the settings for several days without success.

Fortunately, this add-on is available as a replacement.
It doesn’t offer many setting options, but I don’t need them anyway. It’s supposed to display my Instagram posts properly in a widget, and it does that.

Very quick to set up and it works perfectly!
Thank you very much!
