Hello, here is my test to see how zapping works. Rizful is awesome 🤩
Discussion
strangely your lightning address seems to have invisible characters in it.. the LNURL goes to https://rizful.com/.well-known/lnurlp/%EF%BB%BFjinformatique .. 
Ok so now I changed it again in the profil. First I cleared it, then saved and then I typed it manually, no copy/paste.
Please let me know how it goes on your end ?
can you try pasting in your rizful address again pls
