Bug description

Sending message in group chat fails with duplicate error messages. Unable to solve the issue since the error message is very unclear.

Steps to reproduce

• Created group chat with 12 members
• Sending a message from Signal-Desktop seems to fail. At least there are error messages.
• Sending messages on Signal-Android works fine!

Actual result: Group chat message is tagged with "Message not send". Two times!
Expected result: Message should be send to all participants without error message. Or it should be explained, how to solve it.

Screenshots

Platform info

Operating System: ArchLinux x64
Browser: chromium 50.0.2661.102-1
Signal version: 0.12.1

The underlying error is that one the group members is not registered.

[2-4601]

This is solved (or handled temporarily) in Android by just ignoring the error caused by the unregistered member: https://github.com/WhisperSystems/Signal-Android/commit/021942fd4358ac88eb1642933731b8a9fa39622f

It would be better to highlight the unregistered user so one could remove him from the group

Groups are egalitarian. There's no group administration. You can only leave a group yourself and thus an unregistered user cannot leave a group.

I have to get some kind of feedback, otherwise I cannot tell who recieved the message.
Further it would be nice, that after I got the error message, I could skip sending messages especially to that user or that my client automatically removes that user until he or she reregisters to Signal.

I've got the exact same problem.
Further I would like to add that while my phone recognizes the number not being registered, Desktop Client still shows the contact.
When sending something via Desktop Client directly I get a generic error, but no information why the message couldn't be sent.

Thanks!

We now suppress error icons in group chats when delivery fails to an unregistered user, which is consistent with behavior on Android. Additionally, the message detail view (shown after clicking the timestamp) will reveal that the user is unregistered.

Seems to work so far with version 0.14. But I'm still having this red rectangle in front of my message :/

@liliakai could you add a "XY left signal"-message to the non-group chat of the user when signal-desktop notices it cannot send messages?

Everytime one of us is hit by https://github.com/WhisperSystems/Signal-Android/issues/5859 or https://github.com/WhisperSystems/Signal-Android/issues/5531 we have an async group and no one knows until somebody tries to send a non-group message to the affected person or the person tries to message itself.
