How do I? How do I edit my post?

How do I edit the body of my post.
For example, Once I sell an item, how do I add the customary "Sold PF" or similar?
What if I want to update details, pricing, etc.?
When I click on "Edit Thread," only the title appears to be editable.

Instead of using the top menu to access Edit Thread, scroll to the bottom of the ad and click/tap Edit
