hardware coverage

I bought new MBP retina 16" touchbar yesterday (10 Sept 2020) in Apple's Authorized Reseller when I insert my SN to check my hardware coverage, the SN is correct but appeared "Purchase Date not Validated", Please update your product purchase date by following the link, and then I insert my purchase date but always appeared "We’re sorry, but we are unable to complete your request at this time. Please try again later." I have tried several times, until this day (11 Sept 2020) still can't validate the purchase date...why???

what i'll asking now, is it automatically validate itself OR we must validate by ourself? FYI when I bought it I receive paperless purchase detail that include detail purchase and insurance for my device by email, is it good enough for warranty claim? but I can't know my Apple warranty is....?

thx
