I’m not sure, maybe it is a feature of the premium version. If so, please let me know..
If I try to add a media file from media library there happens nothing. No action, simply nothing. Adding images works fine but videos ( mp4 ) doesn’t work.
Would be great if someone has an idea how I can solve this issue.
Videos are not supported by email clients. With the pro composer block you can add an hosted video in the email just copying the video link, but inside the email there will be only the video cover and a link to the video.
