Uploading feature is not working!!!

I purchased this app to use the upload feature to put pictures and videos on my Instagram from my Macbook. It doesn’t allow you to do that. Also you can’t add additional accounts. I’m a little bummed! To whomever it may concern, please fix this problem so I can enjoy what I paid for. Thanks in advance!
