AlpineQuest & OfflineMaps

I've been using this app on my Samsung S10e as well as a Samsung Tab Active. I am a marine contractor and I use it to get land bearings to corroborate my data - I go on many ships in different locations and some of them have OK nav systems... others do not. I download and use the NOAA ENCs and it's worked well until now - I have a ship to meet in Erie PA and I simply can't get the maps to show up online or offline. Any suggestions? I kind of rely on this app because so many others have serious issues when I get out of service.

Hi and sorry for the delay.
It seems that the render is not good for small scales, however when you zoom enough the map does display fine.
This is also how the official website currently display the map: https://www.nauticalcharts.noaa.gov/enc ... nline.html
Maybe they will correct this at some point, that should be good.
