Twitter cards meta tags missing after last update

I can’t seem to be able to reproduce the issue on my test sites. Could you post your site URL here, so I can have a look? Could you also let me know what Jetpack modules are currently active on your site, and what other plugins you use at the moment?

If you want your site URL to remain private, you can also contact us via this contact form:
https://jetpack.com/contact-support/

Active modules:

Carrusel
Enhanced Distribution
Monitor
Protect
Publicize
Spelling and Grammar

I’ve just sent a contact form. Waitting response.

By the way, I’ve updated another site and the same issue appears.

Thanks!

As long as Publicize is active, the Twitter Card tags should appear. However, if you use another Open Graph / Twitter Cards plugin, Jetpack will stop outputting its tags and let the other plugin do the job.

If you do use another Open Graph / Twitter Cards management plugin, I’d recommend checking the plugin settings to make sure the tags are enabled there.

If that doesn’t help, no worries: we’ll get back to your email soon, and my colleagues should be able to offer more help since they’ll have more information about your site and its plugins!

I don’t use any other plugin to handle OG, just a little piece of custom code to add twiiter:site meta tag; I’ve included that piece of code in the contact form message.

Why this topic has been marked as resolved?

By the way, OG keep working well, only Twiiter meta tags are missing.

It seems there is bug. The support team has submit a issue in github for it: https://github.com/Automattic/jetpack/issues/4895
