First of all thank you for creating such an amazing system.
We have an odd issue where users are receiving multiple notifications of the same action. Sometimes they are getting notification from posts or topics that they are not even subscribed to or ever made any response there. These notifications are not sent to email or browser alarm as they appear in notification center. Only the notification center receives all these duplicate notifications. Other issue is that when user clicks on “I have read these notifications” nothing happens.
We are unsure how to address this issue. I have check this topic but our discorse is always up-to-date.
