Video won’t load randomly in Astra Theme

Hi there! Using Astra Theme and Astra Pro Plugin, blog archive pages will randomly not load the featured video. Somethings they show nothing/blank featured section, if you refresh the page they will load again. I though as Astra is such a popular theme you may want to have a look at it.

Thank you!
