Proposal

Please re-state the problem that we are trying to solve in this issue.

App returns to transaction thread, then app freezes.

What is the root cause of that problem?

It comes from https://github.com/Expensify/App/pull/53108. On IOS, we call onModalClose with a delay then we navigate to the scan page first then we call dismissModal here. That cause we go back to the TransactionReceiptPage and now the modal is hidden which is the freeze.

https://github.com/Expensify/App/blob/c8e8517e872c6a9dd739d2745ddd302058ac64de/src/components/AttachmentModal.tsx#L388

https://github.com/Expensify/App/blob/c8e8517e872c6a9dd739d2745ddd302058ac64de/src/libs/AttachmentModalHandler/index.ios.ts#L11-L15

What changes do you think we should make in order to solve the problem?

We should only call onModalClose with a delay when it's not receipt attachment

if (!isEmptyObject(report) && !isReceiptAttachment) {
     attachmentModalHandler.handleModalClose(onModalClose); 
} else {
    onModalClose();
}

https://github.com/Expensify/App/blob/c8e8517e872c6a9dd739d2745ddd302058ac64de/src/components/AttachmentModal.tsx#L388

What specific scenarios should we cover in automated tests to prevent reintroducing this issue in the future?

What alternative solutions did you explore? (Optional)

Reminder: Please use plain English, be brief and avoid jargon. Feel free to use images, charts or pseudo-code if necessary. Do not post large multi-line diffs or write walls of text. Do not create PRs unless you have been hired for this job.

@Beamanator Can we add InteractionManager.runAfterInteractions for each onClose event instead of using it within AttachmentModal?

[Beamanator]

Mmmmm i mean yeah if that would be cleaner, that would work well! But using it within AttachmentModal like suggested above might make it so we don't have to remember to wrap onClose outside of AttachmentModal in the future, right?

[huult]

@Beamanator Yes, you are correct

Confirmed this is fixed in staging

@youssef-lr is anyone due for payment here? I'm not really sure!

[melvin-bot[bot]]

Skipping the payment summary for this issue since all the assignees are employees or vendors. If this is incorrect, please manually add the payment summary SO.

[zanyrenney]

Closing, as this is only Yousef and me as assignees, payment is not due. Thank you for your hard work, @youssef-lr!
