Limitations for Youtube
Component uses Youtube Data API for some of its features. This API has daily quota. Excess of quota would result in inaccessibility of API-dependent features for all users of the component (quota resets at midnight Pacific Time (PT)).
With that said, some features that potentially may result in high quota usage are limited or disabled unless custom Youtube API key is specified.
If custom Youtube API key is not set, component retrieves playlist content using RSS. This is legacy way to get playlist content, and it is limited to 15 videos. Thus update may result in a gap if playlist was not updated for a long time.
