we did some zap tests on this note… we made six attempts to⚡zap this note, at donate@izindlovu.org, over a period of about 1 hour. 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://pay.lightningcheckout.eu/lnurlp/api/v1/lnurl/cb/5ENJTj ). your server did not produce an invoice, thus the zap failed. the error we got was "Amount 1000 is smaller than minimum .". 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.
