This is a backend issue. lastMessageText returns an empty string when the message is deleted.

📣 It's been a week! Do we have any satisfactory proposals yet? Do we need to adjust the bounty for this issue? 💸

[melvin-bot]

@AndrewGable, @paultsimura, @RachCHopkins Uh oh! This issue is overdue by 2 days. Don't forget to update your issues!

[melvin-bot]

@AndrewGable @paultsimura @RachCHopkins this issue was created 2 weeks ago. Are we close to approving a proposal? If not, what's blocking us from getting this issue assigned? Don't hesitate to create a thread in #expensify-open-source to align faster in real time. Thanks!

[RachCHopkins]

@AndrewGable can you please take a look?

[muttmuure]

Is this really unexpected? I am curious why we feel like we should change this behavior

[muttmuure]

I vote we close this

[melvin-bot]

@AndrewGable, @paultsimura, @RachCHopkins 6 days overdue. This is scarier than being forced to listen to Vogon poetry!

[RachCHopkins]

@AndrewGable do you agree that this should be closed?
