Why I didn't see Auto-Renewable Subscription in iTunes Connect

I have found answer:

When you want to sell something, but you haven't sold anything before.
You should open iTunes Connect -> Agreements, Tax, and Banking.
I think you have got Master Agreements -> Contracts In Effect -> only row with Contract Type: Free Applications

Apple doesn't give you access to functions for sell anything. Your App doesn't have access to products in iTunes Connect -> Your App -> Features -> In-App Purchase

Decision: You have to sign new contract in iTunes Connect -> Agreements, Tax, and Banking -> Contract Type: Paid Applications and fill fields [Contact Info, Bank Info, Tax Info]

Note: You should have 'Legal' role as a user. Then you will see "Request" button. If a role is only 'Admin' (without Legal rights), you may see only "View" button, and you won't be able to sign a new contract.

After that: you'll see Auto-Renewable Subscription in Select the In-App Purchase you want to create.

Note: If you don’t see an option for Auto-Renewable Subscription, you probably need to complete some contracts for your account.

Press Cancel and select My Apps from the top-left part of the screen. Then pick Agreements, Tax, and Banking from the options.

Make sure all the contracts are complete, especially the Paid Applications contract.

When you’re done, the status may show as “Processing”. Even so, you should be able to return to the In-App Purchases page and create a new Auto-Renewable Subscription.

If you don't see the Auto-Renewable Subscription option, ensure your developer account has accepted all applicable contracts and have provided tax and banking information in the 'Agreements, Tax, and Banking' section of App Store Connect.
