Instagram message is confusing

On the Instagram for Business module, I see the following warning:

“Please note that your image must be hosted on a publicly accessible URL and you cannot host your images on Google Drive even if the file is shared publicly because Instagram API is not able to download files from Google Drive. The same applies to Dropbox URLs.”

Yet, I’ve seen countless YT videos that seem to make this work just fine using GD and/or DBX.

Even some people in this community admit they make it work with one of those choices as well.

So, looking for clarification from Make.com as to why they are putting that warning on the module interface.
