Ive been holding off downloading the new version but as I have seven days left I took the plunge last week and have already noticed a diminishing of detail on the charts. Eg on a fishing mark of mine:
The old screen shot:

and the new screenshot of the same location
and more of a worrying safety issue, Chinaman's Hat, a large structure just north of the shipping channel out from Sorrento?Portsea only becomes visible on the chart when the map is expanded right out! It doesn't even appear on the chart when zoomed out! Now in my view this is bordering on criminal negligence. I notice that the on line web app maps still contain the finer detail as my old app did.
Has any one else noticed a dumbing down of details for their area with the new version?
