EngageOne Video "Vanity URL" creation not working


Various sales people were trying to use the EngageOne Video dashboard, located at and experiencing a problem trying to create a "vanity URL" which was hooked to a print advertising ( campaign type.


It's wasn't working for some, but was working for others. Any ideas on what could be the problem?

1) Vanity URLs are limited to 255 characters or greater
2) You cannot create a Vanity URL that has already been created by someone else
