Thank you for the response! I do have have nostore set up for my primal npub, and the extension in browser generally works on web. In the cashu.me that I just set up, in the settings under nostr>your nostr keys I only see Wallet Seed phrase-generate nostr key pair from seed” (which is default selection and I think my new cashu wallet generated a new npub there) or “use your nsec - dangerous.” I don’t see an option for signing in with another existing key/my nostore credentials, to use the primal npub.
