Discovering the cause of the 5 RCS thrusters shutting down with only 4 of them being able to restart is the current focus of things, because the spacecraft is no where near running out of helium.

It's all still within the scope of this test flight's objectives, so they technically aren't wrong to say things are going well even when they've found issues.
