Apple Pay

The transaction shows that it was made on Saturday evening of a 3-day weekend.

Would not expect any bank to post the transaction until Tuesday - possibly that night - meaning you’d see it on Wednesday

It may be due to the fact that the 27th, 28th and 29th were not business days (all weekends or bank holidays). For information about cash transfers, see the following from: Transfer money in Apple Cash to your bank account or debit card - Apple Support

Check your bank statement to see if the transfer has been processed and deposited into your bank account. Bank transfers aren't deposited on bank holidays or the weekend. See holidays observed by the Federal Reserve on federalreserve.gov.

If you don't receive an Instant Transfer after 2 hours, or you don't receive a 1 to 3 business day transfer after 3 business days, contact Apple Support.
