I use TfL journey planner regularly, but over the last couple of weeks I've found I can't change the time settings. For example, on the screenshot attached, when I click "Arriving", "Today" or "12.45" to try to change the settings, nothing happens - it's totally unresponsive. I've tried it on 2 different browsers.
Is everyone else getting the same problem? I'd report it, but don't want to waste their time and make myself look like an idiot if it's just me having the issue.
