Slight technical correction, it not a BIP39 phrase, it’s an Aezeed phrase (since LND uses Aezeed which has additional info such as wallet birthday encoded in it). Another BIP39 wallet won’t recognize it as a valid seed, the wallet would also need to support Aezeed, such as BlueWallet or another LND instance.
