I've been working on this myself over the last month. One thing I'll tell you, is keep resubmitting. For some reason, we've been able to suddenly get 5 merges approved this month, with one outstanding.
You'll get the 'not eligible' message one day where you can't even submit a request to update business name. Then, the following day, you go in and it will allow you to submit.
Maybe it's the same scenario where you get your request before a different set of eyeballs.
But, my experience, including as recently as this week, is persistence pays off.
