1. On first viewing of the clickup widget, it's typically empty. Typically it displays 'loading...' at the top but does not update. Manually adding a task typically makes them refresh. Sometimes you need to go in and reselect the folder.
2. Periodically when I go to create a task (particularly adding my first one after a restart) it says 'auth header missing' or something to that effect. This doesn't stop it continuing afterwards.
