First Question:
Lets suppose I'm human right activist in Egypt. If I enabled security notification in WhatsApp and other person's phone is captured by authorities but they cannot unlock it so they make it that user lost their phone.
Now, if I send the message to that user, is this message received by other party with warning that is not encrypted or it is not delivered at all?
Second Question:
Is there any guarantee that server cannot change settings on the client?

It's delivered and then you see the warning. > Is there any guarantee that server cannot change settings on the client? No. Prior to this story I would have assumed there would at least be some risk of being caught by security professionals, but I guess the security community would be falling over itself to explain how the backdoor was an accident or a legitimate usability choice.
