So I entered my course description then previewed it... looked ok but I wanted to make changes... so I rewrote/reformatted the course description, hit "save" then "preview"... and the preview reverted to the OLD version! So I tried again, deleting the entire course descrip and pasting it back in... saved it... preview still reverts to the original. Keeps doing this even after I logged out of Udemy and restarted my computer! Any guesses why this is happening?
