I've just re-subscribed to Rockfax Digital prior to a trip to Portland, and the Cuttings Boulderfield is unusable.
It's pot-luck if the topos will load for anything beyond Church Ope. (In other crags, the topos in each sector load just-in-time as I scroll through them. For the Boulderfield this mostly doesn't happen.) Half the time the app just crashes, either while loading the topos, or when I tap on one to open it.
I don't have this problem with any other crag, and suspect that the issue here is memory management, because the boulderfield is a huge download, and while my phone isn't ancient, it's a few years old and wasn't top spec when new. The Lighthouse Area (also in Dorset Bouldering) which has half the number of problems has been split into separate downloads (which makes finding all of it confusing when compared to the UKC crag page, but that's a separate issue), so maybe the cuttings boulderfield needs splitting up as well.
I have the guidebook ordered, so will hopefully have a backup, but it would be nice if the app worked.
