In the group chat that I was invited to, I’m fairly sure I was following none of them.
I meant that I received a notification from someone I followed and since I don’t pay much attention to some posts, I dismissed it. Dismissing this notification also dismissed the ghost DM for me.
We’re probably talking about the same DM thread anyways considering your notification history
I also have a ghost notification. This notification should disappear on its own without me needing to use some obscure workaround (which right now I have no notifications to perform that on).
It’s unlikely we’ll be able to invest engineering resources into this since this is not very pervasive (caused by edge cases of being removed from a DM while it is unread) and we don’t own the source code in this area. I recommend following the workarounds posted above.
You can try to find exact repro steps for the current Discourse version and posting that to the Discourse team at meta.discourse.org if you are passionate about solving the issue.
