My app release was rejected due to the description. I edited the description to be more verbose, and saved the changes.
However, I can not find out where to "resubmit" this rejected release.
Where would I do that? I don't want to create a new release, if all I have to do is change the description.
After fixing the issue for my release (missing description), I actually had to go to "Publishing Overview" and from there was able to find the button "Send for review" to submit the newest release.
