Changes to Instagram feed in Theme Editor
Because Instagram has discontinued its legacy API, if you entered an Instagram access token to the Instagram feed section in the Theme Editor, then the Instagram feed no longer displays images. You can use a third party app to add an Instagram feed to your online store.
We recommend that you remove the Instagram feed from the Theme Editor to prevent display issues in your online store.
This doesn't impact sales channels like the Instagram channel. Instagram feeds installed by third party apps might not be impacted.
