Linking to an LNURL
What are you putting in as the link?
LNURL:lnurl1dp68gurn8ghj7ampd3kx2ar0veekzar0wd5xjtnrdakj7tnhv4kxctttdehhwm30d3h82unvwqhkymmnw3hkuamfdejs2dw7d3
Try lowercase lnurl at the beginning. I don’t know how it works but uppercase was an issue for me today.
It seems to work with Lnurl:lnurlsbfjrifh
