@felixdkatt Sites you provided doesn't support OpenGraph protocol as it is.
Facebook debug tool is not about OpenGraph protocol only.
Facebook and iMessages do additional work on some common scenarios for sites that doesn't support OpenGraph.
To check site against OpenGrpah protocol check this one:

OK, i think i have fix for that.
There are websites that are using "name" instead of "property" key in <meta ... block>
Also, sometimes websites are using capital P i < meta Property > and here regular expression is caseSensitive.
So here are my adjustments @marty-suzuki @felixdkatt
In OpenGraph.HTML.swift
change implementation of property regex like so:

static let regex: NSRegularExpression? = { let patterns = [ // "" & "" "(?:content\\s*=\\s*\"([^>]*)\"\\s*property\\s*=\\s*\"([^>]*)\")", "(?:property\\s*=\\s*\"([^>]*)\"\\s*content\\s*=\\s*\"([^>]*)\")", // name instead of property "(?:content\\s*=\\s*\"([^>]*)\"\\s*name\\s*=\\s*\"([^>]*)\")", "(?:name\\s*=\\s*\"([^>]*)\"\\s*content\\s*=\\s*\"([^>]*)\")", // '' & '' "(?:content\\s*=\\s*'([^>]*)'\\s*property\\s*=\\s*'([^>]*)')", "(?:property\\s*=\\s*'([^>]*)'\\s*content\\s*=\\s*'([^>]*)')", // "" & '' "(?:content\\s*=\\s*\"([^>]*)\"\\s*property\\s*=\\s*'([^>]*)')", "(?:property\\s*=\\s*\"([^>]*)\"\\s*content\\s*=\\s*'([^>]*)')", // '' & "" "(?:content\\s*=\\s*'([^>]*)'\\s*property\\s*=\\s*\"([^>]*)\")", "(?:property\\s*=\\s*'([^>]*)'\\s*content\\s*=\\s*\"([^>]*)\")" ] let pattern = "meta\\s*\(patterns.joined(separator: "|"))\\s*>?" return try? NSRegularExpression(pattern: pattern, options: [.caseInsensitive]) }()
