It looks that there is no chat to be displayed in focus mode

[bondydaa]

yeah if there are no unread chats then i don't think anything should be showing up in the LHN

[bernhardoj]

This only happens on an account without a concierge chat. Concierge chat should be shown by default

[situchan]

what's the production behavior then?

This only happens on an account without a concierge chat. Concierge chat should be shown by default

in the video the concierge chat is shown at the bottom of the LHN when the video starts, also if there isn't a chat with concierge then that's a different bug altogether since every account gets created with a chat with concierge on the back end.

Hmm, you're right, I didn't notice that

also if there isn't a chat with concierge then that's a different bug altogether since every account gets created with a chat with concierge on the back end.

The way I reproduce it is:

1. Set preference mode to #focus
2. Log out and re login
3. It will show empty LHN

Because #focus will only load minimum chat that will be shown on the LHN and concierge is not included

what's the production behavior then?

Same empty LHN with my repro steps above

[bondydaa]

okay discussed the bug here https://expensify.slack.com/archives/C049HHMV9SM/p1704906122169579 and sounds like yes we agree this is a bug.

The LHN should should the last chat you opened if there are no other unread messages.

[bondydaa]

I can confirm on web v1.4.24-0 doesn't do this and properly shows the last chat in opened in the LHN so seems like it might be something specific to mobile code.

[bondydaa]

We've opened an internal fire room b/c others are reporting similar-ish behavior here even on 1.4.23-2 (desktop) where chats in the LHN are disappearing. Not even just in #focus mode either.

[bondydaa]

There is a good chance this is fixed by a back end revert that we are going to deploy shortly.

Once the deploy is done, I'll bump the issue and see about having it re-tested to confirm.

[bondydaa]

@lanitochka17 can you retest this again and see if it's still reproducible? the backend deploy has finished and so it should be fixed 🙏

I am unable to reproduce on staging!
