Apple Stores have run into an unexpected issue on iPhone launch day—they didn’t receive enough iPhones. Multiple customers have reported to have received an email saying their iPhone won’t be ready for pick-up at the 8 a.m. window due to “last minute logistical issues.” Others have gone to the Apple Store and were turned away because the store did not have enough units.

Just yesterday, many customers were saying their iPhone XS devices that were originally scheduled to be delivered on launch day (September 21) were delayed until Monday, September 24. Many of those orders were stabilized with the delivery date changing back to Friday, only for more issues to crop up.

In the email for the delay, Apple said pick-up could be updated for later on Friday or over the weekend, hopefully meaning customers won’t have to wait too long to go pick up their new iPhones.

Here’s the full text of the email Apple is sending out:

Thank you for your recent order with the Apple Store. We know you’re excited to pick up your new product. Unfortunately, due to some last minute logistical issues, your order will not be ready for pickup during your check-in time. As soon as your order is ready for pickup, we’ll let you know via email. We apologize for the delay in getting your new product into your hands. We’re working quickly to resolve the issue.

The situation will be fluid throughout launch day. If you did order an iPhone XS or iPhone XS Max, keep on checking the status to see if your iPhone becomes available today.
