A month ago I was able to validate three cards.
At first it was only giving me the usual error message “Unable to render Card preview”,
then for some reason it started working, and I validated three cards.
For several weeks, the cards were showing on my tweets perfectly.
Then about a week ago, the cards stopped showing on my tweets,
so I’ve been trying to validate them again.
Now all I get is the usual error message “Unable to render Card preview”.
Is there anyone on Twitter who can look into this and figure it out??
I’ve already verified the twitter:card fields are in the pages in question.
Also, I haven’t seen the TwitterBot visiting like it used to.
Perhaps @andypiper may have some insight??
