If you click on the “up arrow” in the upper right corner of the quote it won’t jump to the quoted section of the quoted post, but it should jump to the post.
For example, try this post
https://meta.discourse.org/t/beginners-guide-to-install-discourse-on-ubuntu-for-development/14727/260
* after the jump up, try clicking “1 reply” and the down arrow in the inserted post
If a post is a reply to a previous post in the topic, and you click on the “curved arrow” that post should insert just above the post that is the reply.
