In case, you have paid the OBD Сar Doctor PRO iOS but don't see pay-functions, do following:
- Go to the app Settings
- In the end of the list find Buy Subscription
- At the next page find the button Restore Subscription – click it and after this, try using pay-functions.
If this doesn't help - write to our forum, describe your problem in details and in the Settings find Send Log-fine, send it to us and we'll help you.
Thanks!
