Many people experience this. Using Visual Editor for previews is often absurdly slow, upwards of a minute in some cases. From a UX perspective, there is little meaningful difference between:

  1. freezing for over thirty seconds then successfully showing a preview;
  2. freezing for over thirty hours then successfully showing a preview; or
  3. freezing permanently.

No reasonable web view should ever take that long. It is unsurprising if people conclude that the software died and close the browser tab without finding out whether it might eventually complete.
