I can't get my nautical charts to work anymore, they were working as of late last year.
It works if I add my service into https://www.arcgis.com/home/webmap/viewer.html, but my code no longer works. It displays the basemap but not the nautical charts, with no errors.
Attached is the cut down version of my code which I believe was working until recently.
Thanks for any advice anyone can offer.
