I gave you proofreading rights. But we had a discussion recently about this, and the consensus is that new translations will be incorporated, even if they are not proofread. (it is hard to prove this 100%, but there is anecdotal proof that non-proofread translations are used)
If a modification is not incorporated in a release, it is more likely that either something went wrong technically, or the translation was pulled for release before the modifications were made. Most of the time you get a call to translate new segments about 2 weeks before a planned release, but actually pulling the translation happens a week or so before release. Any modification after that, will not be incorporated.
Normally, you can contact them into WTI website. Go to the tab discussion and click on button [ + Start a new discussion ]; add a topic, write your comment and post-it to the "Portuguese Crew" or just select two members with proofreading.
