If i update og:image or og:title of a website an rescrape the url with facebook linter, in Facebook the data/the preview is updated. Unfortunately i can't find a similar solution for WhatsApp. If i repost a link with updated metadata in a WhatsApp-Chat, the preview shows the old metadata. I am not sure, if this is a problem with local- or online-cache.
Does ne1 knows, how to refresh meta-data for WhatsApp, if renaming the URL is not an option?
I found a solution:
If i delete all of that links in my whatsapp-chat/group-media and repost the link, the preview is refreshed and shows the new meta-data on repost.
So i guess WA caches the meta-data only local and not online like Facebook. no need for a debugger-tool for WA.
Can someone confirm?
