Drive from ipad

Hi, I have tried several browsers from the iPad (Safari and Chrome) and on both the handling using an Apple Pencil is very erratic. The screen becomes unmanageable. If I connect an external keyboard and mouse the experience improves quite a bit, but it's still not as good as when I connect from a PC or Mac.

Every time I click on the bar or press the interface to advance a candle there is a bounce all over the graph. When I right-click on the chart, the context menu appears but you can't manage the menu well because another Apple Inteligence writing tools box appears on top of it.
