Hello @Hilly 

can you please confirm whether you have created these polls in Slido hose-mode on our website first? Or you have created them in the Powerpoint directly? 

Each poll should have an individual holding slide in Powerpoint and should be launched one by one. Also in case you have created them in the host-mode you should be able to see the between the existing polls as shown here: https://app.vidcast.io/share/9aa58506-e7bd-46c2-997b-2706745a2043
