Ultimate Social Media Plugin will not connect to Instagram

Could you please check if the URL entered here https://www.screencast.com/t/3Pfwfx6nq is correct?

It appeared to be complaining about Instagram, but the problem was Facebook. I had left the first Facebook box “Visit my Facebook page at…” open, because I wanted people to share my blog on their Facebook – not leave the blog to visit my Facebook. So I hadn’t put in my Facebook url.

For instagram, it wants the full url, not @name.

The plugin asks for the Instagram URL, please see https://www.screencast.com/t/0ZAWHWp3DJ.
