Instagram announced that it's discontinuing its "Guides" feature starting next month, so that's something to consider with your IG strategy.
Instagram Guides will disappear on December 15th, existing guides on profiles will be converted to a "Collection".
Instagram first launched Guides in 2020, and it was a method to create thematically highlighted content and present more in-depth material in a very engaging, interactive way.
Guides offered an alternative to feed display, giving creators and brands ways to publish explainers and image collections with short text descriptions. Guides also can be published in Stories, offering a different route for participation.

Clearly, though, they haven't connected with users, and Instagram is ending support for the feature, with Collections being a somewhat lesser alternative.

It did have promise, but I suppose it's the stats that dictate things here, and people just arent really showing much interest in more expanded brochure-type content, more similar to Pinterest, on IG.

So if you have any Guides on your profile it's time to download them or update them into Collections format.
