I'm working on this website and I'm trying to use the open graph protocol. I've managed to get the thumbnail images and meta-tags for Facebook and Twitter, but it has been impossible to get it done for WhatsApp. I can't get neither the thumbnail image nor the description of the website. I'm working with a small size image, added all op codes as recommended. Can somebody please give me a hand telling what is wrong with my code?
