Within the last couple of weeks, I lost the ability to scroll right to see all the columns in my Yahoo Finance Portfolio. The right arrow keyboard key won't scroll right like it did in the past.

I could still use a workaround like zooming out until I can see all columns, but then the text would be too small for me to read. I could also create another portfolio that contains the remaining columns that I cannot see. However, being able to scroll is much more convenient, and it was available up until a couple of weeks ago.

I have the same problem using both Firefox and Microsoft Edge browsers. Both browsers are up to date.
