And, the URI scheme works with the Blockcain.com wallet so you can put it back on the list.
Now we have two people claiming it works and one who says it doesn't. I will just wait for the next reply from someone who is interested in checking before I put it back on the list. Like in sports, let's see if the result will be 3:1 or a draw after all.
BlueWallet also works (obviously, mainnet wallet only, not LN), so you can add it as well.
BlueWallet has been added. Thanks for the tip.
