Hi there, I also have same issue when trying to fetch. I did not chnage any settings or something I were scaping with shis settings 2 years. I suspect its something with the last plugin update.

EDIT: Google Info Search Terms field were empty, filled it again and scrape were sucessful.

Nice, that sound promissing when i can to assign  ID's :) I already have Rankmath Business so i can do even manual schemas. 

Thank you very much! :)
