I am using tinyurl.com to automatically pass links to a feed @TryLoud
Whilst the card validator shows the correct information for: https://biggreenexchange.com/offer/details/37, the tinyurl equivalent does not work in the card validator: https://tinyurl.com/h7c4zaf/37
The tinyurl.com link works when pasted into the browser.
Any ideas what could cause this - as the cards do not appear in the twitter feed.
I have a similar system working on my own site @sellmyretro and it works fine - for example, compare the card validation for http://www.sellmyretro.com/offer/details/21625 with the tinyurl equivalent http://tinyurl.com/y8nwe39/21625
