We are currently experiencing issues posting images to Instagram if the files uploaded is a png one
If your Instagram post failed to send and received the following error message, "Facebook error: Fatal (code -1, subcode 2207001) errorUserTitle=Instagram Platform API Error, errorUserMessage=Unable to download image from the url: https://s3.eu-west-1.amazonaws.com/files.XXXX.png
. You may try again later." we recommend that you create another post with a jpeg file.
We are working with Instagram to resolve this issue. Thank you for your patience during this time.
