I paid $7.99 for all premium but still get a watermark in the video.
Apologies on any delay in getting back to you. Are you still having issues on removing the watermark from your Movie? Can I please have you try to direct your attention to the icon with 3 dots on the top corner and click on "Build a Movie". To remove the watermark kindly drag the slider from the "Remove App Logo" then hit on Make Movie.
Yes, finally found it a while ago.
