Proposal

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

Chat - New marker displayed briefly when chat is opened

What is the root cause of that problem?

When user A received a message, this useEffect is triggered because the length of sortedReportActions is changed.
Here we always call readNewestAction API if the report is unread without checking the last action is created by current user or not

App/src/pages/home/report/ReportActionsList.js

Lines 147 to 152 in 2dbfb4b

	if (ReportUtils.isUnread(report)) {
	if (scrollingVerticalOffset.current < MSG_VISIBLE_THRESHOLD) {
	Report.readNewestAction(report.reportID);
	} else {
	readActionSkipped.current = true;
	}

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

We should check if the last action is not created by current user, we will not call readNewestAction API

App/src/pages/home/report/ReportActionsList.js

Lines 147 to 152 in 2dbfb4b

	if (ReportUtils.isUnread(report)) {
	if (scrollingVerticalOffset.current < MSG_VISIBLE_THRESHOLD) {
	Report.readNewestAction(report.reportID);
	} else {
	readActionSkipped.current = true;
	}

Hi @MonilBhavsar and @allroundexperts, do you think you could take a look at this deploy blocker. It seems to have been caused by this PR here.

[roryabraham]

This is an deploy blocker so it supposed to be hourly. Not sure why melvin-bot decided to change that, but he's not supposed to. Anyways, reassigning this one to you @srikarparsi

Edit: Created an issue for this: https://github.com/Expensify/Expensify/issues/310178

[roryabraham]

[roryabraham]

Not seeing enough movement here and it's the middle of the night for @MonilBhavsar so I'm going to jump in and try to help push this forward

[marcaaron]

If the revert also solves this -> #25688 (comment)

Should we just revert?

[roryabraham]

I think I seeing that @JmillsExpensify said that the change is needed for wave1?

Edit: found the comment: https://expensify.slack.com/archives/C07J32337/p1692809918214309?thread_ts=1692799992.392829&cid=C07J32337

Bumped to weekly, as happening rarely

[MonilBhavsar]

Making it daily again as we can reproduce by sending successive messages and focussing on and off the chat screen. Also, we want to close the project soon

[melvin-bot]

@gedu, @allroundexperts, @MonilBhavsar Whoops! This issue is 2 days overdue. Let's get this updated quick!

[melvin-bot]

@gedu, @allroundexperts, @MonilBhavsar Huh... This is 4 days overdue. Who can take care of this?

[melvin-bot]

@gedu, @allroundexperts, @MonilBhavsar Now this issue is 8 days overdue. Are you sure this should be a Daily? Feel free to change it!

[melvin-bot]

@gedu, @allroundexperts, @MonilBhavsar 10 days overdue. Is anyone even seeing these? Hello?

[melvin-bot]

This issue has not been updated in over 14 days. @gedu, @allroundexperts, @MonilBhavsar eroding to Weekly issue.

[melvin-bot]

This issue has not been updated in over 15 days. @gedu, @allroundexperts, @MonilBhavsar eroding to Monthly issue.

P.S. Is everyone reading this sure this is really a near-term priority? Be brave: if you disagree, go ahead and close it out. If someone disagrees, they'll reopen it, and if they don't: one less thing to do!

[MonilBhavsar]

This is fixed. No action required here. Closing
