I still use the same email address that was used for registering,
Email address? Are you sure you used an email address when you were creating your wallet?
As you were talking about recovery phrase, I assume you used the
non-custodial coinbase wallet where you don't need any email address for creating a wallet.
Which coinbase wallet did you use?
Their non-custodial wallet or
their custodial wallet?
In their custodial wallet, you must provide an email address and they don't give you any recovery phrase.
In their non-custodial wallet, you don't need any email address and they give you a recovery phrase.
As you said that you had a recovery phrase and also used an email address for creating the wallet, it's not clear which coinbase wallet you used.
