Komento - possible bug regarding email notifications & issues with Cron not sending emails

Hi,

I recently encountered issues with Komento, not properly generating email notifications.
The current setup is that Komento would send email notifications when a new comment is posted, to all users within a specific Joomla User Group.

But this seems to work only if Notify Content Author (in Settings > Notifications) is also checked and set to active.

Is this the wanted behaviour or could this be considered a minor bug? If this isn't a bug, is there a way for Komento to generate (and send) email notifications to only this specific Joomla User Group?

I'm also having issues on a server, setting the cronjob for these email notifications, but I understand servers often cause this. Triggering the cron ~ task URL works from a different server or when triggered manually, but still I just wanted to check if there's an easy solution and what could be the cause for the server not executing the cronjob properly?

This is the exact cron I've set: curl --silent https://www.sitename.com/index.php?option=com_komento&;task=cron

Thanks!
