just started having this issue right now.
Basically whenever I go to chart for ANY stock, it auto takes me to a blank spy chart without any of my drawn lines. Refreshing takes me to the same blank chart. Is this just temp or did I lose all my chart drawings.(I did not clear my browser or anything, using chrome on chromebook). how to fix this?

Also I have already lost my chart drawings before, hundreds of hours of work and had to redraw. Is there any way to save the charting (not just a screenshot) so I don't have to redraw whenever something happens like if I clear my browser?
