Message delays are confusing for users
Feedback from user testing:
Case 1: "From one of the participants of our test:
They had bluetooth and WiFi transports available (3 parties in close proximity). It seemed messages were being sent via mobile data as opposed to bluetooth. This resulted in sometimes significant delays being seen in sending/receiving messages. With ancedotal measurement these delays were seen between 2-3 minutes and 9-10 minutes.
The users expected bluetooth to be used (as they were all physically near each other). These delays did not match how people were thinking bluetooth would be "instantaneous" communications.
It did not affect things too much but confused people.
Can we clarify how messages are sent received when there are multiple transports available?"
Case 2: "UserA was waiting outside UserB's house. UserA sent UserB a message and said there was approx a 2 minute delay, using mobile data."
Case 3: "I've been at a meeting today. Have checked Briar this morning and twice during the afternoon but not been signed in at length. I've just received all the messages from today at 22:01ish. Some of which had occured before I signed in earlier so I should have received them then. I imagine that maybe I wasn't signed in long enough to receive the data package. As a Whatsapp user id expect to sign in and within a minute have received all the updates from other people. So the response time for thread updates in one issue."
