we did some zap tests on this note… we made six attempts to⚡zap this note, at xxx@mannabitcoin.com, over a period of about 3 hours. in each case, we found that your lightning address server did not respond correctly. (the failure point was when we did a get request to your specified callback url: https://mannabitcoin.com/api/payreq/f6b2f543-b014-5349-a161-140f011b3adf ). your server did not produce an invoice, thus the zap failed. the error we got was "Amount is not within valid millisatoshi limits: 100000 - 25000000000". if you wanted to fix this... you could try getting a free rizful lightning address -- https://rizful.com ... if u get it set up, pls reply here so we can do this ⚡zap test again.
