[Solved] Send email notifications about comments to the post author only without him/her having to subscribe to it

Could you please check and leave some feedback for each point mentioned in this FAQ: https://wpdiscuz.com/community/f-a-q/wpdiscuz-subscription-and-email-notification-dont-work/

Thanks for your quick reply.

Here are the answers:
1. We use Elasticemail transactional email service in combination with WPMail SMTP Pro and send out hundreds of emails per day, so yes, we are sure this works. We just checked again and see all emails sent correctly from Buddyboss, WP core,... Unfortunately no from WPDiscuz
2. We waited already several days.
3. We don't use
4. Not relevant as we only want notifications sent to the post author (admin)
5. We tested this
6. Sure
7. Not relevant to this case
8. We don't use
9. First link: we disabled all options there because we only want to send notifications to the post author. Second link: we already have those 2 options enabled.
10. WP_5_WC_COMMENTS_SUBSCRIPTION exists

Maybe also important to note that we use a WP Multisite setup.

Thank you.

Thanks @asti I will ask there.

Another question. Is it possible to put that post author in a WPDiscuz database table so she gets notification emails on EVERY WPdiscuz comment written under a post?

Thanks @asti, I went there but it looks a table with subscriptions to a certain post ID. Is it also possible to add the author email address somewhere so she gets email notifications about ALL (WpDiscuz) comments on the site?
