We've had two reports today where content just isn't loading and learners are getting "stuck". The content has all been released and on our LMS with hundreds of learners going through it without any issue for some time now. Neither lesson is very complex, so they shouldn't be too prone to error. It doesn't seem to be limited to a specific browser. I've republished, just to be safe, but it doesn't seem to have made a difference. Has there been some sort of funky browser updates recently that I may have missed?
