I am trying to share ionic generated pages to Facebook via an RSS feed. Facebook reads sharable information from the documents Open Graph properties placed within the header from the url referred to in the XML feed. I implemented a routine that updates the header meta tags on location change. Still Facebook cannot process the document using the debugger at https://developers.facebook.com/tools/debug/og/object/ although all relevant information is available.
I found that the reason is a so called canonical href (A ) tag, means that “#” making FB to redirect to the main url.
