Duplicated message received

[an-eternity]

Noticed an issue - one message was sent, but two copies of this message was received.
Received with aTox v0.8.0 running on Android 11 (installed from Google Play).
Sent with qTox 1.18.4 (toxcore 0.2.22, Qt 6.8.1) running on Windows 10.
UDP mode enabled in both clients.
Both clients connect via symmetric cone NAT.

This, however, could be a qTox related issue.

For now can't provide any more specific technical details.

Thank you for the report! :)

What likely happened is that due to network issues, the receive-receipt wasn't received on qTox's side, and qTox correctly resent the message that it didn't know aTox had received.

aTox doesn't really have a way of knowing if a message is the same message, or if it's a new message with the same text, so it'll happily add it to the chatlog again. There has been some talk of ids in messages to make that possible, but there's nothing in place right now.

tl;dr, this is likely harmless and is unavoidable right now.
