What you need to know about the old Classic View as a Host?
If you are currently on Adobe Connect Version 11.2 or higher, all your rooms are set to the new Standard View by default. However, as host you have an option to disable it and fall back to Classic View in native desktop applications, if at all, you need to use old Flash content (swf, flv, f4v), Flash based Custom Pods or PPTs. Your choice of Standard or Classic View as a host will be applicable for all participants in the room.
This support for Classic View will end in Spring 2022 with the Adobe Connect 12 release.
