Unable to sync iPhone after upgrade to iOS 10

Since upgrading to iOS 10 I cannot sync my iPhone OmniFocus app with the OmniFocus servers. Even when I email myself the sync settings the app asks to set up syncing every time I start it and never shows any data.

I’m sorry about this, @patrickmay! Have you gotten in touch with our support team at all? If not, please send them an email – we certainly want to get you up and running again as soon as we can.
