Payment links via Stripe in UK often fail on Post Code check

Hi,

we have just too many online payment links via Stripe failing with postcode check.

Stripe warning looks like this:

Blocked by postcode checkThe issuer authorised this payment even though it failed the postcode check. Usually, failed postcode checks may indicate fraudulent behaviour. You can configure whether you would like to block authorised payments upon failed postcode checks here.
It is by far the biggest reason for failure. But disabling the rule is considered the highest risk.

Could there be something wrong with the form passing the info to Stripe? When I give the customer direct Stripe link, it is ok with the same card.

BTW I also see another warning in Stripe:

Integration improvement available
This transaction is missing customer email address, which affects fraud detection.
