David -
PG 9 section 7.1 covers what we require as evidence but in my experience there are times when we will need a full copy specifically when it is shown to include additional instructions and the download you refer to does not explain what those are.
Is that perhaps the case here re the last requisition/application you refer to? If it is then it might be worth making a note that where no additional instructions have been included then the download info is fine. But where 'more' is included then we will need a full copy of the LPA
