My mobile apps have previously integrated with Instagram Sharing to Stories both on iOS and Android. Recently, some users started seeing the “The app you shared from doesn't currently support sharing to Stories.” error on the UI after they tap on the sharing button and land in Instagram, as shown here.
In another instance, ther users are seeing the error message "The app you shared from doesn't currently support sharing to Instagram." instead.
What could be the issue here?
I'm expecting Instagram to open the stories editor with the preloaded media shared from my app, but instead, it's showing the main feed view with the error message on the bottom.
This is due to a Facebook App ID requirement recently enforced by Instagram on January 30, 2023.
You can find their blog post at https://developers.facebook.com/blog/post/2022/10/10/introducing-important-update-to-Instagram-sharing-to-stories/, as well as their developer documentation: https://developers.facebook.com/docs/instagram/sharing-to-stories/.
To fix this issue, you would need to register your app on the Facebook developer console at https://developers.facebook.com/, obtain a Facebook app ID and pass it as the source_application param in your integrations.
