"Could not set up Apple Pay - An error occurred while setting up Apple Pay

Touch ID is set up, but as I mentioned, I am not able to select the Touch ID options for "use with Apple Pay," or "iTunes." When I select "Apple Pay" in Touch ID settings, I'm prompted for my password which I enter and then a checkmark shows in the box. However, if I navigate back to Settings and then back to "Touch ID," the box is unchecked. The box for "iTunes" will not show a check at all when I click on it.

I've also tried signing my computer out of iCloud, restarted, then signed back in and restarted, just in case.

I'm guessing that if "Apple Pay" is not selected under Touch ID, the "Add a Card" process under "Wallet" is not going to work.

Update: Apple customer service had me reset the System Management Controller (SMC) by shutting down, then powering on while holding down the power button for 10 seconds, then pressing the power button once.

I then logged on as I do normally, added a checkmark next to "use with Apple ID" in Touch ID preferences. Verifying that the change was accepted, I returned back to System Preferences then went back to the Touch ID preferences panel, and the checkmark by "use with Apple ID" remained checked. Then I went to Wallet system preferences and was able to successfully Add a Card.
