Hi @Bastet
You have now been moved up from a Basic User to a ‘Member’ which gives you more posting permissions.
There is no ‘mark all read’ on this new platform because of the way the software counts a users interactions and sets their user level according to how much they interact.
Just reading posts can increase your user level, but you do have to read them.
See the link below for more details about it.
You can still easily filter for new topics, unread topics, etc.

I’ve found the quickest way to do it is to set them as bookmarks on your Hamburger menu.
See this thread for how to do that:
