Sadly Instagram is going on with deprecating their API.
After December 11, 2018 it will not be possible anymore to display an Instagram feed (latest 20 posts) on a website. (https://developers.facebook.com/blog/post/2018/01/30/instagram-graph-api-updates/)
Will IFTTT applets using instagram still work after the deprecation?
I could not find any information about it and IFTTT does not mention the deprecation at all (except https://ifttt.com/blog/2016/05/a-change-in-how-instagram-works-with-ifttt).
