I’m seeing a similar issue in a similar time period, except that while I do see the address I don’t see the second line of the address. My site generally has 30-40 orders per day and usually one or two of them each day are missing the apartment number. It took me a lot of digging to finally realize that what they all had in common was that they paid with Stripe — those who paid via Paypal don’t seem to have the issue, and it’s not all paid with Stripe. Thus I’m not 100% sure it’s the express checkout, but I just turned it off because it’s becoming a significant time suck with needing to request clarification on addresses all the time.
