I just tried paying Strike and Alby lightning addresses and both didn’t work. Tried using the mint.enuts.beta mint.
Static addresses are part of the lnurl specs and work in eNuts.

What does not work are the bech32-encoded lnurls

The transactions failed because the enuts mint runs on the lnbits demo server and it sometimes fails during payment routing or goes down for maintenance.
