Investigating
This morning we received numerous reports that users are unable to start the Pear Deck presenter from the Google Slides Add On. We have been able to reproduce the issue and are investigating the cause.
As a workaround, the PearDeck App (https://app.peardeck.com) can be used to present through the Sessions page or by using the "Open existing file" button.
