Our iOS app pulls in HTML pages allows sharing them via a “share this page on Twitter” button. When tapped,the Twitter share function comes up and it tries to render the page’s card. After about 5 seconds, it gives up and closes down but does not crash the app. The web page has passed validation, though our dev vendor believes the problem is with a map plugin on the page (which comes in via an iFrame.) Can I tell Twitter to not try to render a thumbnail of the page, or otherwise prevent shutting off?
Here is an example page that crashes sharing: https://asuevents.asu.edu/content/lunch-and-learn-university-sustainability-practices?eventDate=2016-11-30T12%3A00
