I downloaded the app. I'm not a fan of it making me register outside the Shopify environment. I also accept Exchanges for up to 2 years, but they have set an unknown limit on this. Next, when trying to edit the Exchange/Returns during initial setup it kept being stuck in a loop and there was no way to break it. App is currently not working as intended. There may be something off with the redirect after you initially set your choices.

Good App. Liked the quick support from team. Seamless process for customers and all logistic partners are also available so works good for me.
