How to mark all unread topcis as read?

I have many unread topcis since they were auto migrated and I cannot find a way to make them as read without dismissing new notification for them. Did anyone figure it out?

I’d like to know as well.

Unfortunately, I haven’t found a way to mark all topics as read yet either.

There seems to be a hidden “Unread” page: and I think this page is supposed to have a “Dismiss All” feature, but unfortunately for me that page is empty (no “Unread” topics, no “Dismiss All” feature).

In Read topics there is Dismiss... button and then you can confirm but without disable notifications check.
