Elfsight YouTube Video Gallery

Looks like there are some serious issues with this app. Setup was breeze but after about a day, the app stopped showing videos from Youtube. Whenever I tried to add a new widget, it was displaying errors like "Unfortunately, an error occurred: Daily Limit Exceeded. The quota will be reset at midnight Pacific Time (PT). You may monitor your quota usage and adjust limits in the API". This was even after I entered Youtube API token in the Preferences tab. Looks like they have hard-coded a generic project number in the call to Youtube API. And there is no way to change that. That's why it is hitting that limit. I am also trying their support for the past 2 days and still no response. I will keep my rating as 1 until they fix this issue.
