No theme html / css section

I can’t find the html / css editing part of the second theme disappeared with the update.


Do you mean this

If you are using a remote theme then editing has been removed. You can read about this in more detail in the topic below.


The html / css editing part in the second theme has disappeared.

We can’t guess what your second theme might be. Did you read the topic linked above?

Except for the main theme, none are edited.
