You may have uploaded a video to YouTube, that you ultimately want to add to a campaign, and are seeing a message stating "This video is being processed - It will be ready in about 10 minutes."
If after waiting some time, your video still does not appear on your campaign, try the following:
In your YouTube account, ensure that the video is set to public. Private videos will not show on your campaign.
Remove the YouTube link that you previously added to your campaign.
After ensuring the video settings are correct, re-add the link to your campaign and then republish.
If you are still having issues, please contact firstname.lastname@example.org.
