Ctrader Web chart issues

Hi,

I am using Ctrader on Brave version v1.62.162 (latest). Everything seems to be working fine except the chart. Most often than not, I am not able to click on the existing drawings on the chart, alerts or positions. Hovering over them does not seem to trigger any action. This behavior is persistent but highly irregular. For example, with a position and 2 alerts on the chart, one alert may work properly (that is, hovering over it will produce additional buttons to move/share/delete it) and the other alert won't react to the mouse hover. Hovering over the position may show your PnL and additional actions only to stop working a few seconds later. All issues can be fixed by reloading the page or switching to another symbol, but the problems randomly return within a few seconds. Being in Japan and having both a good Internet connection and a powerful PC, I can't think of any other reason for this than compatibility with the browser (which I would very much not want to change just for Ctrader). 

Thank you for the help in advance
