Thanks. It just seems weird that for a standard, default wallet in Sparrow, for the public key it shows xpub by default, instead of zpub. These are for Sparrow created native segwit wallets, addresses starting with bc1. And the derivation path of m/84'/0'/0'.

And it's definitely confusing Blue Wallet. I assume when you give Blue Wallet an xpub, to create a watch-only wallet, it assumes that you're trying to use legacy wallets. So it sets the derivation path to m/44’/0’/0’, and the addresses start with 1.

And of course it doesn't find any transactions.
