I'm not suggesting it as a long-term solution, I'm suggesting it as something that can get your issue cleared away while you wait for a bug fix or other permanent solution. If you'd prefer to enjoy slow syncs for a while longer, be my guest. Otherwise, try emailing the support ninjas at
omnifocus-iphone@omnigroup.com or calling them during West Coast business hours. I promise not to snicker if they make the very same suggestion :)
