When you move between stock/instrument chart tabs they do not retain their scale so you have to resize every time you go back into them. Could the Desktop Web App be updated to retain the scale settings.
It feels like the Mobile and Desktop Web Apps should be on different code bases to enable the Desktop App to be functionally better and for the UI to be more appropriate for a desktop. It’s currently a bit like using a phone mobile app on an iPad. Alternatively allowing customers to use third party platforms, such as TradingView, would provide a better experience.
