Will this work as intended to block and then cancel the job if currentStateFlow changes?

currentStateFlow.takeWhile { it == CurrentState.IncomingRing.WhatsApp }.collect()

It's worth being precise with the terminology here: this code doesn't block (it suspends) and it doesn't cancel a job. It should work, though. You can also simplify to this:

currentStateFlow.first { it != CurrentState.IncomingRing.WhatsApp }

State flows never emit duplicates, so by definition there'll be at most one emission of the CurrentState.IncomingRing.WhatsApp value before it changes. That probably doesn't change your implementation, though.

Oi sorry, I meant to paste the full code, which has a cancel() after this line, oops. Ah neat idea with the simplification.
