Action Performed:

Pre-Condition: Have another account you have access to and two different devices

1. Access https://staging.new.expensify.com/[](javascript:)
   and Log into a valid Account A on Device A
2. Click on the chat with the other Account B
3. Disable internet connection by turning off Wifi on Device A
4. Send some messages, while offline, to Account B you have access to
5. Enable internet connection by turning on Wifi on Device A
6. Log into Account B on device B and verify the messages from Account A

Expected Result:

4. While sending messages Offline the user should see a message under the text box stating that he/she is in fact offline while writing

5. Once logged into Account B on Device B the user should have received the message from Account A

Actual Result:

4. While the user is typing in Offline mode on Device A, he/she does NOT see any message whatsoever stating that they are offline (This also happens on prod build https://new.expensify.com/[](javascript:)
   )

5. Once logged into Account B on Device B the user has not received any message from Account A (Note: If the tab is refreshed on Account A on Device A, after reenabling Wifi, the entire text message that had been sent while wifi was disabled disappears as if it were never written)

Note : If the user send a message after the wifi is turned ON, only the message sent after the Wifi is ON will be received
The Account A used had 2FA enabled and this bug is reproduced for individual DM's or Group Messages. Also it is NOT reproduced vice versa, from iPhone to Mac, only from Mac to iPhone

Seems like the user being offline is not getting detected and is related to:

• [HOLD for payment 2022-03-22] [$500] Connection drop is not detected - Reported by: @Santhosh-Sellavel  #6059

Report comments are only going to be persisted if we know we're offline
Since they are not, they are getting lost (like any other non persisted request) when we refresh

Solving the ticket above and making sure internet connectivity is detected correctly would solve the current issue

[kidroca]

I don't think this is deploy blocker

• code around Network connectivity detection hasn't been changed recently
• network related packages (net-info) haven't been changed recently

Also it's stated that the bug is already on PROD: "This also happens on prod build"

[marcochavezf]

Thanks for that @kidroca! Yeah, this is not blocker, I'm going to close the ticket because the issue is already being addressed in the issue that @kidroca linked.
