The discussion revolves around the behavior of Discourse when clicking on a topic title. Dante_Dante pointed out that clicking on a topic title takes them to the last post instead of the first one, inquiring if this is a bug or a feature.
Moin and maiki clarified that Discourse is designed to take users to their last read post in a topic. However, users can navigate to the top of the topic by clicking on the timeline slider, the number of replies, or the topic title at the top while reading the topic.
Additionally, twofoursixeight mentioned that clicking the top of the timeline also navigates to the top of the post quickly. There is also a category setting that can take users to the first post if there are no unread posts.
I have a topic that has many post, when I click enter instead of showing the first post, it shows the last so you have to scroll up.
Is this a bug or discourse is supposed to work like this or there is a feature I can click to force that the post in the topic start from the 1st post not the last
Hi Dante Dante. 
Discourse is designed to take you to your last read post in a topic. If you’ve read all the posts, it will take you to the last post. This is to help users pick up where they left off in a discussion.
Also, on the right side of the topic, there is a timeline slider that you can use to quickly navigate to the top (or any point) of the topic.
While reading a topic you can also click the topic title at the top to navigate to the first post.
There is also a setting that takes your users to the first post if there are no unread posts Navigate to first post after topics are read, category setting
