Tester didn't know whether message had been uploaded to Mailbox
The tester was confused with the process of sending a message while the other contact is offline. He was expecting to get feedback from Briar to know if the message has been saved to Mailbox. He opened the notifications drawer on the Briar phone but didn’t find anything, then he checked the Mailbox app but didn’t find feedback there either. While he was waiting, he noticed an hourglass icon near the message and didn’t know what that meant. He thought it indicated a disappearing message. After I asked a follow-up question on how he understands if a message is delivered, he let me know that one checkmark indicates that the message is delivered and two checkmarks that the message is opened.
After the other contact came back online, he noticed that the message was delivered as he saw the checkmarks, but he was wondering if the message was sent directly from the app or if it was transferred by Mailbox and he didn’t find any way to understand this.
