Reproduced, seems also potentially wave 5 worthy as a bug in the core request flow

So, I've investigated the problem. Actually, looks like there is a small miscommunication between the backend and the app. For this logic to notify the app and send the latest changes, we use the Pusher. It works properly all the time, except one scenario. When the app goes offline, then back online, there is a period for a reconnection. Once the app has connected again successfully and even received other kind of messages, this update for a money request preview is missed. Looks like the Pusher sent it before, but the app was offline. As I understand there is no logic to sync data one more time. Anyway, we need to ask a backend developer, to clarify this.

@Ollyws, @thienlnam, @MitchExpensify, @rezkiy37 Whoops! This issue is 2 days overdue. Let's get this updated quick!

[MitchExpensify]

@thienlnam what is your take on @rezkiy37 's backend related observation ?

[thienlnam]

That's a problem we're solving with our own onyx update events - where each separate device's updates are stored and delivered once the device is online. I imagine this scenario is one that would be fixed once we eventually migrate it over to our own onyx updates.

What API command is being called here?

What API command is being called here?

The app calls a "RequestMoney" command to request an IOU.

@Ollyws @thienlnam @MitchExpensify @rezkiy37 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!

[thienlnam]

I looked at the video, and it seems like this will likely get handled once we eventually migrate RequestMoney to send pusher updates via Auth.

Additionally, considering how specific this bug is - I don't think we need to address it right now. It does inform the user correctly that they were unable to delete the request

cc @MitchExpensify Thoughts on closing this?
