Tricky Situation!
My advice is upload both together. Anyways POF should not take too much time to get. In case the bank/any agency is delaying, better to go and show them the letter (also include a typed/handwritten application seeking documents). They will give you on the same day.
Thanks! The problem with the PoF is that the bank in which I have my funds isn't in India, and also, they don't offer statements in English. So there is the additional issue of getting them translated from a certified translator. All of this will take longer than the 1st ADR deadline :/
