      We’re aware of an issue with presenting when using Slido's Google Slide integration. When using our Chrome Extension, you are unable to launch Slido interactions. The rest of the service remains unaffected and is operating smoothly. We have identified the issue but unfortunately are unable to update it immediately and hope to have it resolved within the next couple of days. In the meantime, there is a workaround available so that you can run your presentations. Workaround - Disable the Slido Chrome Extension - Open your presentation in Google Slides - Click the green Present button directly from the Slido sidebar Please note, that once you do this, your Slido interactions should activate and load as expected, though your transitions/animations will not work. Thank you for your patience as we work through this and we're sorry for any inconvenience.

      Our Google Slides integration should gradually be returning to normal, although it can take a number of days for the new version of the chrome extension to reach you. This is something that we don't have any control over so if you find the present mode still isn't loading for you, please continue to use the following workaround: - Disable the Slido Chrome Extension - Open your presentation in Google Slides - Click the green Present button directly from the Slido sidebar
