Thanks for your reply, Olga. Our problem is Yoast SEO Premium has stopped be activated on our site and I can’t get it reactivated. So far, Yoast Support is stumped. Today I gave them a guest admin account and they are investigating further. If you’ve encountered this problem with other Royal users, please point me to the solution that worked for them. I don’t think our theme is the problem, especially after reading your description of Royal’s caching. If Yoast Support does need more from you, I’ll let you know.
