We had plans on implementing Instagram as a new provider, however the deprecation of the Instagram API Platform was announced:
Some endpoints has already became deprecated:
and the “Basic” scope which would be required to read a user’s own profile info and media will also become deprecated in early 2020.
Currently we know no alternatives for the Instagram API, as it seems, some services will be offered directly by Facebook via the Instagram Graph API however it won’t be a direct replacement. This means, it can’t be used for the same purposes as the legacy Instagram API.
