Sometimes things go wrong
It might happen that someone encrypted a mail for another recipient but mistakenly sent it to you and so you're not able to read it. Or a signed message you're receiving was modified without your knowledge. Or anything else could have gone wrong. In these cases we're trying to be as helpful as possible by providing good explanations of what happened.

Whenever we detect that something's not right, you'll see a banner with an error message, letting you know what the problem is.
