@dylanexpensify FYI I haven't added the External label as I wasn't 100% sure about this issue. Please take a look and add the label if you agree it's a bug and can be handled by external contributors.

Proposal

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

The group chat disappears from LHN even after splitting a bill and can't be found on the search page.

What is the root cause of that problem?

When we create a new group chat, the notificationPreference and visibleChatMemberAccountIDs from the BE response will be hidden and empty. After doing a split bill, both data are unchanged. It will be updated once we trigger the OpenReport request by reopening or refreshing the page. If notificationPreference is hidden, it will render nothing.

App/src/components/LHNOptionsList/OptionRowLHN.tsx

Lines 60 to 63 in 22cb01c

	const shouldOverrideHidden = hasBrickError || isFocused || optionItem.isPinned;
	if (isHidden && !shouldOverrideHidden) {
	return null;
	}

If visibleChatMemberAccountIDs is empty, we won't include it in the search results

App/src/libs/OptionsListUtils.ts

Lines 1513 to 1515 in 22cb01c

	if (!accountIDs || accountIDs.length === 0) {
	return;
	}

We previously encountered the notificationPreference issue here when adding a new comment to the report.

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

We can use the same solution from #29681, that is to update the notificationPreference to always if it's currently hidden when splitting bill.

if (ReportUtils.getReportNotificationPreference(splitChatReport) === CONST.REPORT.NOTIFICATION_PREFERENCE.HIDDEN) {
    splitChatReport.notificationPreference = CONST.REPORT.NOTIFICATION_PREFERENCE.ALWAYS;
}

And to show it on the search page, based on @marcochavezf comment here, we want to replace visibleChatMemberAccountIDs with participants, so we need to update the way to get the IDs in OptionsListUtils.

App/src/libs/OptionsListUtils.ts

Line 1520 in 8206580

const accountIDs = isSelfDM ? [currentUserAccountID ?? 0] : report.visibleChatMemberAccountIDs ?? [];

const accountIDs = isSelfDM ? [currentUserAccountID ?? 0] : Object.keys(report.participants ?? {}).map(Number);

(we probably would need to do the same for assign task, send, and request money, but depends on how BE do it because for request money, BE never updates notificationPreference)

@dylanexpensify Huh... This is 4 days overdue. Who can take care of this?

[dylanexpensify]

Apologies, I've been OOO sick, but am reviewing today!

[dylanexpensify]

Hmm @m-natarajan can you confirm this is still reproducible?

[dylanexpensify]

Hm so the chat->bill create shows in the Search but not LHN (disappears). cc @arielgreen
