When logging into the Going. app, you can use your Apple account. Apple will then ask you if you want to hide your email address. Choosing this option will log you into the app using an address with the suffix @privaterelay.appleid.com, instead of the address used to purchase the ticket.
Each ticket purchased on Going. is linked to the specific email address provided during the purchase and will only appear in the app registered to that address. So, if you hide your email address during login, you won’t see your ticket in the app.
Please register in the app again using the email address associated with your ticket.
