Greetings, I have been using wordpress.com for a while, and Now I found a problem, I think you are updating something because the button to add media is not working for me.
I usually clicked the button to add media and then a small windows shows over the screen to select my pictures to upload. Is not happening. but if i click the button with right click and choose "open in a new tab / window", then the window to upload files appears but is useless.
I tested this with mozilla firefox and google chrome and is the same problem.
