Hi ajbachert,
Sorry to hear about that!

You can sync the iPhone app manually by swiping down in any view—the left navigation bar, a list view, or a task's details or notes. If you do that, does the task show up in the web app?

Or does it help if you update the task and sync? For example, changing the priority or adding a tag—does that change force the task to sync?

If not, can you contact us so we can help with some more specifics? Thanks!

I've experienced this, too.
