All paid Animoto subscription plans include Animoto watermark removal and 1080p HD downloads. If your video still has the watermark after upgrading, you will need to export your video again.
Exporting is what updates your video to apply the latest version and features. If your video had a watermark, the upgrade will not be applied to it until you export it again.
To export your video again, click Edit Video from the My Projects page, then Share, and Export. Now your video should not have the watermark anymore.
If your video still has the watermark after upgrading, you may need to check that you are working in the correct account. Users on the Professional Plus plan will need to create their video in the Team Workspace to access all of the upgraded features. You can check your plan on the Account page.
