Hi @aamid_riyaz
I am sorry you're unable to link your Debit card to your PayPal account. In some cases, our internal security systems may block these actions for your protection. The unusual activity can be accessing your account from a different region, usage of unrecognized or restricted networks like VPN, public networks. Also, try with trouble-shooting steps like clearing cache and cookies and logging in to a different browser. If you still face issues, you can contact us through phone or PayPal message center to seek assistance from a specialist.
Thank you
Punith
