Not working today

Not working with my iPhone ( 18.2.1 ) at all. Try to access a chart and it just goes black . I could find no help in the app, nor from the grander universe

Another Don’t do it

I’ve been over this app 1000 times and I still can’t get it to download anything other than a blank page on the chart I select. I clicked download, it says downloaded, the file appears nowhere on my iPad and when I try to open it I get the blank page that downloaded. contact for the developer is nonexistent.
