Stunning Presentation Design Using PowerPoint Morph - Changing Perspectives 

Sadly at the moment only Microsoft Teams supports the Morph transition with uploaded online content. The two workarounds are either to use screen sharing in Adobe Connect, which generally works very well, and means people will see exactly what you see. Or convert the short slide sequence to a video and embed that video back into the presentation, so that you capture the transition effects in a standard video format that all tools can play back. It's best to keep the video as short as possible, so ideally save out just the two slides where you have the Morph transition, then File > Export > Video and convert those two slides into a short video.
