How do I use Poll Everywhere with Google Slides, PowerPoint, and other slideware?

Note: The Poll Everywhere add-in for the iOS version of PowerPoint Office 365 is not available for UMBC users. Presenters using an iOS mobile device to present polling activities should use the Poll Everywhere Presenter app, which is separate from Office, or should use a laptop to present Poll Everywhere activities.

Update

Poll Everywhere released an updated Chrome Extension on March 15, 2023. Please update your Chrome Extension if not using automatic updates.
