I received my federal return though i did not receive my nj state when inquiring on state site for nj there still is not a date for refund

NJ only updates their website when your refund has been Approved and issued. So it is still in process.

So I was told Thursday that my nj state refund was approved but it’s not showing on the website. When does the site update?
