If you get a Tinder code that starts with RT, it means it is restore purchase token. Here are the steps how to activate Tinder restore purchase code.
How to activate Tinder RT code:
-Log in to your existing Tinder account using a web browser.
-Go to your account settings. Under “Account Settings,” find the “RESTORE PURCHASES” option.
-Enter the provided code in this field. Press “Enter”
As you can see it is very simple. Be noted RT codes are not activated under promo code field, but under restore purchase field.
If you dont see restore purchase option, it means you are most likely iPhone user. In that case, login to your Tinder account via web browser (not Tinder app) and you will see restore purchase section.
If you still dont see restore purchase field even from browser, then you should contact Tinder support and ask about the issue as restore purchase field is default feature in Tinder and everyone has it.
Only users not currently subscribed to an active Tinder subscription can activate. “RESTORE PURCHASES” function is unavailable for active subscription account.
