The most recent listens on my account are from 10 months ago. I have scrobbles as recent as yesterday, but I've tried several times to update with the Import bookmarklet (always make sure it's the current one), and it never seems to do anything. I don't even get a pop up. It's possible I have some plugin that's interfering. I've tried disabling adblock and "disable html5 autoplay" plugins, but that hasn't seemed to make a difference. I typically use Chrome. I can't even figure out how to make it work with Edge right now, or I'd test that too.
