Yesterday I was running a Collab session and tried to upload the excellent “your session will start soon” animated GIF which @Gillian Fielding has shared, but Collab now splits the animated GIF into separate slides, and won't play it as an animated.
I'm sure I've read something about this elsewhere but can't remember where - is this a bug or a change of functionality? It would be a shame to lose the ability to upload animations.
