I can’t seem to validate a URL for twitter cards. I have already been approved for summary cards but would like to also include summary_large_image so I tried the validation process (https://dev.twitter.com/docs/cards/validation/validator) but get an error.
Error: Invalid card type.
It doesn’t say anything else (no problem tag etc.) so I’m not sure where to begin looking. It’s essentially the same code used for summary card types, which works without issue, but with “summary_large_image” as the type instead.
Any ideas where I’m going wrong? Do I have to reapply for each card type I want to use?
