We have been starting out using the Live View and have found that when using PowerPoint 2013, the slides in the attached browsers do not appear to follow those in the projected image. It is more obvious when there is a simple build in the slides (e.g. lines of text appearing) but can also apply to complete slides. An update can be forced by a refresh of the attached browser but that isn't always helpful. It's not always consistent. We set up four browsers - two on android, two on iOS. Between them, there was significant variation as to what was updated and when. The PowerPoint slides themselves were not that difficult. We were running Windows 10.
The corresponding stage view wasn't impacted.
Has anyone else seem this and more importantly, does anyone have a fix?
