They are the same post type, so the code is the same, og:images are all .jpg files that comply with the required dimensions and filesizes as far as I was able to find out about that. I have read to keep images under 2Mb. Any suggestions? This one brought a thumbnail image to the WhatsApp chat This one did not
I read the documentation from Rank Math and found and checked details against what I read there, and have searched around the internet, and consulted Open AI. I have not found an answer.
