When purchasing a subscription renewal, make sure that the email you enter matches your current email on file for OTR Diagnostics. Apple Pay, Shop Pay, and Google Pay tend to autofill the email address associated with those services and it does not always match the address we have on file for your account.
If you do purchase a subscription under a different email address, you can contact our support team at support@otrperformance.com or by calling 586-799-4375 so we can correct this for you.
