what's going on recently with the analysis ? lots of hangs and freezes on both mobile and PC ?
There have been a lot of changes to the analysis board recently.
Any context might help to iron out bugs, for example a screenshot (most useful with the developr console opened using ctrl + shift + i).
Or other details (even if they may seem random): browser, specific games or positions, if the local engine was running, engine settings, multiple lines, new textual lines enabled?
