(My site is not previewing meta tags and description when I enter the url on social apps like Whatsapp, Facebook, the link is not previewing meta data)
Other Information
(other information and details relevant to your question)
But I am using a custom domain not a free domain and I have some other sites that I created in May 2023, the meta tags worked perfectly without any issues
I believe you used Cloudflare with your custom domain during that time?
It is true that sites using Cloudflare were exempt from that security system, but due to a recent change, Cloudflare is also no longer exempt from it. To learn more why it happened, please read this thread:
Yaa , it’s true that time I used cloudflare and everything worked smoothly, so do you mean for now there is no way to show meta tags previews even if I have a custom domain not a free subdomain , Is there a way out or?
Yes, unfortunately, there is no way to disable that system in free hosting anymore, even if you have a custom domain and use Cloudflare. This means Opengraph meta tags will not work in most places.
