I am a developer working for the City of Chicago. Every month, on “City Council Day” we promote a page on our website where users can watch live video and view community tweets.
We have, until this month, used the old search widget which worked adequately (though many visitors complained about slow loading times).
I switched to the new “Embeddable Timeline” widget and received feedback from MULTIPLE people (including the City Clerk herself) that the widget did not ever load for them. There is no one specific browser that was problematic, nor a specific operating system or network. Just dozens of people saying “it didn’t show up.”
I am hoping that Twitter is working to correct this. It was totally embarrassing.
