ContentStudio - Social Media Scheduler

I wanted to love this extension, especially since I've used the one created by Hootsuite for a number of years. However, I've not been able to get it to work. Sometimes the icon is greyed out and even when it turned blue it would never post, there is always a pop up that says "An error occurred Please try again." I don't think it's user error. Regardless, I'd really love for this much-needed extension to work.

We have tried downloading the ContentStudio app in Chrome browser. However, it does not work. It is just showing as the logo icon being greyed out in the top of the browser. When we click on the CS app icon, nothing happens. All our other apps work. This is the only one that doesn't. Please can you fix this? We have tried uninstalling and installing the app many times, but it doesn't work. Happy to change this to a five star rating when the app is fixed. I look forward to hearing back from you. Thank you very much. I appreciate your co-operation with this matter.
