Don't worry, I just put <meta name="twitter:card" content="summary_large_image"> in as raw html and it worked!
Hopefully Elon Musk won't make it that we'll have to pay to use meta tags. LOL
Ahhah I like that solution - especially as it means I don't have to do anything! :-)
If Voice used summary_large_image by default would it be worse in any cases, or a safe improvement, do you think?
