I think this is a bug somewhere.
nostr:npub1gcxzte5zlkncx26j68ez60fzkvtkm9e0vrwdcvsjakxf9mu9qewqlfnj5z does Amethyst "capture" the nostr.com/xxx links and redirects inside the app itself? Why not respect the intended behaviour? Or at least ask the user what he want to do.

Thanks if you will check it.
I did a couple of tests and other similar links seem to work fine: nostr:npub1hfvr8a93geddl4t3kf5jn0awvuuscl5925fu0hay0yw06wkv8w3sr7p9sc
Maybe a regex problem somewhere!
