As host, I start an attendance poll before others join. When participants join, they are presented with the poll. This works for most devices. However on some iPads and iPhones, they see a small message that says "The host has started a poll" which stays on their screen for about 2 seconds. They do not see the poll. I have thoroughly tested using the latest updates. Has anyone experienced this? Is there a setting that needs to be changed on the participants device?
