Two questions

1) With the nostr:npub1mutnyacc9uc4t5mmxvpprwsauj5p2qxq95v4a9j0jxl8wnkfvuyque23vg app on ios does that eliminate the risk of your cache clearing or whatever it is, where you open it up and better have a state backup?

2) if you do have to restore a wallet, and only have the seed phrase, that means any lightning channels are still locked up, no?
