I have paid for subscription of Audible app. When I go to App it says I am a non-member. How do I get it corrected or get support ?

You might want to try seeing if there is something there in the app to activate your subscription

or

look for an eMail in your inbox from the app developer

or

Is this the website online (help section) connected with the particular App you subscribed to:

or

How to contact an app developer – Apple Support

If needed:

If the App came from the App Store:

App Store Support webpage:

(See the "Get Support" link at the bottom of their webpage (below)

App Store - Official Apple Support

All the best :-)
