The issue is, when I use the upload tool at, the part where I need to define devices, countries and languages in the distribution tab, it does not show the submit button at the bottom. It displays only "Loading.." and the options on top are unclickable.

I have been rechecking the content page from different browers and even deleted and restarted the content upload process 2 times. The tool accepts all the descriptive texts, images, icons and even the sis file, but does not display the Distribution Tab properly to proceed for submission to QA. Any clues on how to get this sorted?
