Signal is misbehaving in weird ways

[liori]

Using a supported version?

• I have searched searched open and closed issues for duplicates.
• I am using Signal-Desktop as provided by the Signal team, not a 3rd-party package.

Overall summary

Signal desktop (7.4.0 from a Debian package) stopped showing new messages, doesn't show delivery notifications (yet I verified with another user that messages are delivered), and displays This person isn't using Signal in the Note to Self conversation. Signal Android (7.2.4) also says Send failed, tap for unsecured fallback (yet I verified with another user that messages are delivered).

Steps to reproduce

1. Open Note to Self

Expected result

Can type a note to myself.

Actual result

Observe the This person isn't using Signal message.

@liori Can you email support@signal.org and include a link to this github issue? We'll need to ask some follow-up questions to try to figure out how your account got into this state. Thank you!
