lighting mode is a new 'experimental' feature on there. I have my old standard wallet (singlesig/legacy segwit). when I signed up for lighting it added a new lighting wallet in the app next to my old wallet. Looks like I theoretically can transfer to and from it but can't figure out how to move some out of the old one into the lighting. I was trying to move some sats out of that wallet into my new alby wallet to use on Nostr.
