Research direction

Start by reading issue #168 and the linked comment, then trace how prerender-node handles the two WhatsApp user-agent requests shown in the logs. Confirm whether the differing preview behavior is reproducible and identify the expected response before proposing a fix; the issue is done when both requests produce the intended preview content.

Description

I use the latest versions of node and server Prerenders.

WhatsApp/0, as I see it in the logs is for the mobile App and WhatsApp/2 is for both Web and OSX App (possibly Windows App too)

Will just link my comment into another Issue:
