Button "Read more" and "Related article" - Say What?

Hello there!
I would be thankful for help.

  1. It’s related to this topic: https://colorlibsupport.com/t/change-read-more-button-text/
    I want to change language of this button, but settings desrcibed in last post don’t work for me. When I add new string using these hints, nothing is adding. There is still “No string replacements configured yet”. Did something change since january?

  2. Related article in posts - it’s generally the same question - what should I put into string settings to change it? Alternatively, what is an ID of that element, so I can disable it via additional CSS (it’s not really necessary for me).

Thank You in advice for Your help.
