I think we have similar timelines so maybe mine will help. My AOR was 4th of April and I received RPRF request on 14th June (about 3 weeks ago). I say similar timelines because your AOR is about 3 weeks from mine and you just received RPRF. Immediately after paying RPRF my BGC turned to NA but the status of documents continues to show 'additional documents required...'. I have not been asked for any documents apart from RPRF.
I called the call center last week and they said the incorrect document status is due to a glitch in the system but that the RPRF was well received and the application is progressing as per normal timelines.
Hope this helps
Thanks Abi.. that definitely helps. The challenge that I have is that my BGC has been NA from the start and I haven't seen that change as yet.
