Chris: A film is not eligible for rating until its first release date.
April Flowers (2017) has two release dates listed: a vague release date of 2017 (which is treated as December 31, 2017 for ratings purposes), and a more specific release date of February 9, 2017.
As things are now, your film should be available to accept ratings on February 9, because that is when the film is supposed to be first available for viewing by the public.
If the February 9 date is incorrect, or you have another release date to report that is earlier than that, please submit a correction or addition to the film's release dates.
I hope this helps. Good luck!
