RH 2022.5.28 Issues with Creating and Applying New Variables.

I found the new steps for creating a new variable, which btw, seems a step backwards from RH2020. Anyway, I was finally able to create a new variable but cannot get the new varable on my topic page. Drag and Drop no longer works as in RH2020-another step backward. Found the Apply Variable option, but the Search for the variable is not working. What can I do to get the new variable on my topic page?
