OK this is interesting. I am able to send you sats from CoinOs, but from Rizful... from Rizful I get the error: "The invoice does not match the LNURL metadata (h-tag mismatch)."... It might be the coinos does not verify that before paying... I need to do some more testing with your address and see if I can find the exact issue. It could theoretically be a flaw in how Rizful is comparing the metadata, although this error message is exceptionally rare. Will put it on my todo list.
