Quick question, should I ever throw CancellationException manually?

We have some old network api implementation that throws CancellationException manually when the auth token is missing in our storage

It's better to have a proper exception type

CancellationException is treated specially - https://betterprogramming.pub/the-silent-killer-thats-crashing-your-coroutines-9171d1e8f79b

We do have a proper exception but it is being caught and then the CancellationException is being thrown. I believe it was done in order to cancel all work and log out the user

Throwing a cancellation exception manually can have very unpredictable results, it's definitely not a good idea to rely on it

[Sam]

If you want to cancel something, always call cancel().
