I noticed that the prices are not updated either. Perhaps other parameters too.
Found a solution! I installed the WP Video Gallery plugin and in the WP All import settings, in the “Custom Fields” line, I selected the name “_nickx_video_text_url” and in the value a link to a YouTube video. Thanks to everyone who helped! I hope my decision will be useful to someone.
Good afternoon! The thing is, I do not know where to enter the video preview link. The only place I can register it is in images, but then nothing is simply displayed.
