Under Beginners > NHK News easy I cannot scroll the content of the webpage, so I only see a photo and a couple lines of text. I can make the font smaller, then it all fits, but then it is too small to read. No such problems on MATCHA Japan Travel.

Then again, I cannot scroll the list of "Blogs" or "Spoken Audio" either. How many entries I can see depends how I resize the window.

Testing on a Mac (MB Air - M1) with latest Ventura.
