Hoping that was our problem, I uninstalled the update and rebooted – but no luck.

This technet post mentions it breaks ‘Conferencing Functionality and PowerPoint Presentations’ as well as ‘ White Boarding, polling’ which was caused by KB3142030. Windows 7 however was affected, and I’m not sure on Windows 8, 8.1 or 10. This didn’t seem to affect all external clients (internal was fine), when I tested on Windows Server 2012 R2 from home it worked fine. The tab of the browser showed ‘Skype for Business Web App’ but the page area had nothing. I had an issue recently where remote clients couldn’t connect to Skype for Business online meetings – when clicking the link, all they saw in the browser was a blank page.
