For: All plans
The sample page is where the owner watches their video, with a watermark and no download.
If you edited scenes first: making the page takes a few minutes, because Explaindio makes the scenes you changed again before it builds the page.
If the button is greyed out and says "You can make it once the sample video is ready", a scene is still being made, for example right after Re-voice. Wait a moment. The button turns on by itself.
If it doesn't work: If you see "Add your name and business in Sending settings first", fill in Who your emails are from on Sending settings. The sample page shows who made it.
