When I try to update the reviewers on a pull request, the "Update pull request" button stays inactive. I removed a reviewer and added another, but it says "There are no changes".
Strangely, there are changes (in the form of changesets to be merged) when I view the pull request, but they disappear on the edit page. There are no bookmarks involved here: just two repositories where a branch
X has more commits in my repository than in the main repository.
