Sure Marko,
This is happening when sharing any link to WhatsApp from an Android device. Normally, when you share a link to WhatsApp, it shows a ?site preview? which includes meta description and featured image from post.
I understand that property=og:image should be working fine, because if I share the same link by using an iOS device it works as it should be. Sharing to Facebook or Twitter is also working correctly.
I guess that somehow WhatsApp user-agent is not able to pick the right image from post when generating that preview, and it is something related to page cache, because it works if I disable W3TC. The thing that I can’t understand is why this is only happening when using Android devices, and I tested using three different devices.
For example this one is not working: https://www.aberturasldo.com.ar/puertas-multianclaje-ldo/ and same thing is happening to any blogpost.
Marko, I hope that this help you understand what it’s going on.
Thank you and regards.
