Yesterday, I made two last minute alteration to the Proclaim presentation from my study. By this time, presentation (from a different PC) had already gone on air.
The changes had definitely synced to the Proclaim server (because I printed the revised presentation), but they never made it to the laptop driving the projector — and still hadn't 30 minutes later. In the end, I had to ask them to manually sync.
Is this by design? If so, it's an odd design.
