I just did my first every lightning network payment from a smartphone wallet to a desktop wallet ( 2 different wallets, muun and phoenix )
Can you please clarify what desktop wallet you used exactly for lightning transactions, since Muun and Phoenix are both mobile only wallets?
Maybe it's possible to install them on computer using some Android emulator, but that is not exactly what you would call a desktop wallet.
Muun is mobile only ( Im using Android )
but with Phoenix, I was able to install it via the Mac App Store ( IOS ) on my Mac Mini, and it works great.
