Agree with all you've noted. I'd also add that 'Exit'/'Close' buttons sometimes don't work (I use Firefox btw). Worse, you have to click so many different buttons to buy just one index fund.

In contrast, I can do all that in one pop-up/side panel in Fidelity or Charles Schwab. I have been a long time user of Vanguard (almost two decades) and I wish they revert to their old web UI, which is informative and simple enough to get all the jobs I need to do in an efficient manner.
