Can you explain a bit more about how you say Primal changes user notes?
I did a test just now, publishing an image that was uploaded to nostr:npub1nxy4qpqnld6kmpphjykvx2lqwvxmuxluddwjamm4nc29ds3elyzsm5avr7 but pasting the URL into a note on Primal.
When I viewed the source of the published note, Primal had not changed the location of my image.
Help me understand what the problem is.
