Let's imagine you Googled a product and followed the link to an amazon.com page. Amazon, as well as any other online store, has its own app that is opened when you click the link to the product's webpage. This doesn't allow FastBuy to work as intended, so we didn't want the stores' apps to open up when clicking the links. In the end, we adopted the following scenario: if the internal browser tries to open the, let's say, amazon.com app, the code blocks the app and opens the page via FastBuy.
