Here’s the section from the Terms & Conditions,
>>For a P2P Transfer funded in whole or in part from your Apple Cash Balance, you authorize the Bank to debit your Apple Cash Balance for the amount of the transfer that is funded from your Apple Cash Balance. Other Users are not required to accept money you send them via a P2P Transfer. If a designated recipient is not a User or has disabled the ability to automatically receive P2P Transfers and does not accept the P2P Transfer within seven days, or if the P2P Transfer cannot otherwise be completed for any other reason, the P2P Transfer will automatically be canceled and we will refund the amount of the transaction to your Apple Cash Balance and/or Supported Payment Card, as applicable.<<
It used to specifically state that the 7 day wait period was only the first time the User had a transfer and accepted it. Subsequent P2P transfers would be held for 5 days. I’ll make a few calls to see if it’s now 7 days all the time.
