I accidently sent a message, how can I delete it?
You cannot delete messages. However, when you are the author, you can use "edit" to adjust your message.
There is no function for hiding or deleting sent messages in Rubus completely, but you can alter the content.
Use the three dotted menu on the right side of the message and click "edit" to enter the edit mode. Now, if something was sent by accident and there is no information you want to pass, then just edit your message and overwrite it with e.g. "this message was sent by accident"/"message deleted" to clarify.
If you by chance experience that your message is not being sent/was not sent when you clicked send, then the only reason it gets lost is when you are having a bad internet connection and it in fact was never actually sent out.
