Giphy not working

Hi... I'm trying to activate Giphy for the first time... I've followed the guidance at https://stackideas.com/docs/easysocial/administrators/hows-to/how-to-integrate-giphy-with-easysocial but all I get is a spinning wheel when I click the GIF button front-end.

Is this a known problem?
(I am building a replacement site in a sub-folder /canew at the moment so my usual site login isn't where I am working at the moment)
