Alerts on Comments in Modern Pages?

Here is my solution how you could make alerts on comments for Classic Publishing Site in SharePoint -> https://rasper87.wordpress.com/2018/11/21/notification-center-inside-sharepoint-on-prem/

Having tried a couple of different options I've gone with a Powershell script that uses PnPOnline to retrieve all my modern communication pages and then write any new commentcounts to a separate SharePoint list (or update an existing list item if the post already had comments previously). Then I have an alert setup on the list for any new or modified items. So far works really well. And the script was pretty straightforward to write (luckily, as I am not an expert Powershell guy by any means).

I did try Joao Ferreria's excellent solution and it worked well. The only drawback was that whenever we ran the code it modifies every modern page it checks so our last modified datetimes and users were changing regularly and it played havoc with various 'Most Recent' list views we have.

I found that when I downloaded the SharePoint app to my phone I got alerts on my phone when comments were posted in response to News I posted.  I am following the site but I don't know if that is why. I didn't do anything active to set up the alerts.

What I do is to embed a Microsoft Forms form on a modern page and for each response (i.e. comment) I get it to send an email to me with the comment and it also creates a new list item in a SharePoint list called Comments on the site. It works really well and gives us a record of every comment, who submitted it and whether we've responded. The form can, of course be added to multiple pages. If you want to show a conversation on a page though you need to display a view of the list which works but my solution works better when users don't need to see other comments.

Hi Guys, 

I've built a custom solution to receive email notifications on new comments using Microsoft Flow and an SPFx extension. The process is still manual, it requires a click in a button from the browser but all site owners will be notified if new comments are available. The instructions to implement it step by step are available http://sharepoint.handsontek.net/2018/08/13/receive-comment-notification-by-email-in-modern-sharepoint-pages/.

This is a must fix. My recommendation is to have this setting turned off for the entire tenant. This is an impossible situation where I can't understand why not Yammer is a bigger part of it. A site could have an open Group in Yammer, or a hastag in a Group. The root site could send out to All Company. 

The framework for all solutions on Office 365 for my customers are to have so Close to standard as possible where it is something related to the company's USP that breaks the mold, not standard functionality that should be there.

Imagine the impact of a lot of employees thinking someone cares about their opinion and then nobody replies to them ever because they can't see it? 

Bad design. 

The iterative development that MS is taking for the O365 environment is great on one level, but why would a comments feature not have alerts baked in? Having to play around with APIs and Flows for this kind of feature is just not realistic.

I'll wait until they get it sorted out.
