Could you share a little more about what happened?
Here’s how our nostr:npub126ntw5mnermmj0znhjhgdk8lh2af72sm8qfzq48umdlnhaj9kuns3le9ll experience started….still hoping for a recovery.

No access in nostr:npub126ntw5mnermmj0znhjhgdk8lh2af72sm8qfzq48umdlnhaj9kuns3le9ll to view on chain wallet keys, so no ability to access our wallet outside of S9. S9 backup/restore utility failed to restore due to backup being corrupted and failing checksum authentication.
I’m sorry to hear that happened to you. Hopefully it can be resolved somehow
