Hi! I've been noticing broken image references across our forum. They load fine at first, but after a few hours, they stop displaying. It seems to be sporadic—sometimes the same images work, then moments later they don’t. Any idea what might be causing this? Thanks!

Does anyone know how to change the video thumbnail? I have a video for each lesson in my course, but I can't seem to change how it appears to users before they click on the video. Thanks!
