How to edit Date of Birth info in paypal?

[smartzkool]

Yes I got a reply from paypal that DOB is not a concern to remove the limitation. But I wonder then why they still keep my account limited. I submitted my address proofs, and I linked credit card number using VCC. Now the only one step pending is "confirm my bank account" which I'm not able to do.

Well it is not a concern to add your bank account. It has nothing to do with limitation. You just need to wait a few days for them to process the things you did for removing the limitation. Just wait.
