Why aren't my themes showing up in Ubuntu 20.04 Tweaks?

I recently installed Ubuntu 20.04.2 LTS. I have not upgraded from a previous LTS version, it's a completely fresh install.

I downloaded dconf and all its extensions, and in Tweaks, my user theme shells tab no longer has the triangle which tells you they are disabled and you are now able to select different shells.

In the past, when I had 18.04 LTS, I had to create a themes folder and add it to the home directory and from memory the /user/share folder as well for the themes to work.

I created the the themes folder in my home directory in 20.4.2 and they do not show up in Tweaks, other than the themes that are already there. From what I can see, there no longer is a user/share folder, like there used to be. All I see are links to the themes folder.

So where do I need to place my themes, and in which folder or folders? I cannot seem to find a straightforward answer here after looking at various answers.

There isn't a /users/share/themes folder, but there is a /usr/share/themes. You could try that if ~/.themes didn't work for you.

When you paste a theme in ~/.themes, you should look for it in Applications part of Tweaks and it was at the top of the window but in the new version of Tweaks, Applications part is located below (which is written Legacy Applications) :

So you must be able to see the added theme in the list.
Note that when adding the theme, close Tweaks (if open) and open it again.
