.GIFS broken all of a sudden

Hi! New to the discussion boards - but I've been encountering a (somewhat) random error occasionally that I cannot solve.

I've been embedding .gifs into my Rise courses which work, however there are some days where the images do not render and appear broken. Seemingly totally random days and it's consistent with others on my team (they see broken images when I see them).

I've tried uploading smaller, shorter GIFS and restarting Articulate. It looks like the image uploads at first, but after half of a second becomes "broken" again.

Has anyone ever experienced this? Is this a bug that will resolve itself eventually?
