In reply to conronoy:
Natural England did put a sign up on Thursday evening with the updated restriction but unfortunately it was removed (involving forcing open a sign holder, so seemingly deliberate vandalism) between then and the weekend.
As far as I know the Rockfax app doesn't pull through current RAD info like the UKC crag pages do, so access info just like a paper guide is usual case scenario and checking the RAD is the only way to get up to date info (though of course ideally there would be signs on site too). I think if you have the RAD app (rather than website) it works without signal (assuming you have accessed it relatively recently and it's synced). Lots of bird restrictions change year to year and even day to day as in this case unfortunately.
