I have a simple site up on heroku and I’m trying to get twitter cards working for our press release articles. I’m pretty sure I have everything set up properly because if I use my base heroku URL in the validator (https://sequencebio.herokuapp.com/press/release/2016-08-10) the card shows perfectly fine. However, if I use our actual custom domain (https://sequencebio.com/press/release/2016-08-10) it says it fetched the page successfully, but can’t find any meta tags.
I’ve read through at least a dozen threads on here and tried all of the recommendations, but no success - I’ve hit a wall.
Also, fwiw, the Facebook sharing debugger tool can find the og tags just fine on https://sequencebio.com/press/release/2016-08-10
Hope someone can shed some light on the situation. Thanks in advance!
