Cant authenticate JP Bank

So I setup a JP bank account and received my card. Want to login to the website and so need to authenticate with the app but getting this error. The thing is I already gave them my phone number and location during the opening process. What do I need to do? Ive never seen an option to setup phone number in an ATM. Do I need to go to a JP bank atm specifically?

Heres the error message:

当行に電話番号のお届けがない、市外局番が登録されていない等の理由により、お手
続きを進めることができません。ATM等で口座にご登録の電話番号をご確認ください。

Thanks in advance.
