A facebook share url for my site is for eg:
www.mysite.com?q=123
However, facebook is not calling the url with query parameters i.e ?q=123 is missing.
Is there a way to make facebook to use query parameters
The issues was meta tag og:title was assigned to "name" instead of "property".
Strangely, this somehow made facebook to ignore query parameters in URL.
Assigning meta tags to "property" made it work.
