Xerte page preview on social apps

Hey folks, I just shared a Xerte page on WhatsApp and noticed it doesn't have a meaningful preview. Might be a nice extra.

Hi Joe
a couple of quick comments...
I might be wrong but that SITE_PREVIEW_TITLE in your screenshot looks like you haven't added a title in the Learning Object Title field.
Try adding an optional Twitter card (including a suitable image) and then try sharing the link again. Make sure you publish before sharing.
Does that work for you?

Thanks for the reply Ron. Not sure how to add a Twitter card, it's a bootstrap page, so does that not have them?
The project is populated as below, if that is an insight.

Hi Joe
The Twitter card functionality was added in Xerte 311x xot.xerte.org.uk/play.php?template_id=81#v311section6
So the Twitter card option exists in 3.11x and 3.12x but not in 3.10.5 which you are using.
For reference the option is available in both Bootstrap and XOT projects and if you want to test and see if/how it works in WhatsApp (and Twitter) share this link to our Bootstrap demonstrator xot.xerte.org.uk/play_137#page1
HTH

Ah, I will wait for an upgrade. Thanks for your help!
